CHAPTERS

Free trade with China: extension of markets or distortion of them?
The debate opens with the core philosophical disagreement: whether “free trade” with a non-market economy like China actually supports free markets or undermines them. Cass argues that treating free trade as synonymous with free markets breaks down when the trading partner is state-directed.
- •Free trade is often assumed to be the natural companion to free markets
- •China’s non-market structure can transmit distortions into market economies
- •The key question is whether trade rules and incentives remain market-consistent
- •Trade policy becomes inseparable from political economy when partners are state-driven
- 0:51 – 3:50
American Compass’s mission: prosperity through family, community, and industry
Cass explains the founding premise of American Compass and its critique of the recent economic consensus. He argues that maximizing efficiency and corporate profits doesn’t reliably produce broadly shared prosperity or support the social foundations of flourishing.
- •American Compass aims to re-center economic policy around family, community, and industry
- •Critique of “excessive faith” that markets automatically deliver good social outcomes
- •Efficiency/profit-maximization can produce unequal or socially damaging results
- •Markets can support non-economic goods (family/community), but don’t guarantee them
- 3:50 – 4:44
Does manufacturing revival actually strengthen families? A challenge from international examples
Smith presses Cass on the claimed connection between restoring manufacturing and improving family formation or community health. He points to Germany and South Korea as countries with strong manufacturing bases yet severe social problems, questioning causal links.
- •Questioning the manufacturing → family/community causal pathway
- •Germany and South Korea as counterexamples (high manufacturing share, low fertility)
- •Distinguishing goals: growth/national security vs. social renewal
- •Prompting Cass to clarify what manufacturing policy is supposed to achieve
- 4:44 – 8:56
Econ 101 vs. the modern trade reality: comparative advantage, industrial policy, and assets-for-goods
Cass argues mainstream trade teaching relies on simplified models that miss how modern manufacturing advantages are built through deliberate policy. He also emphasizes that trade deficits can mean exchanging goods for assets (debt/equity), changing the welfare story.
- •Comparative advantage models often assume natural-resource-driven specialization
- •Modern manufacturing advantage is frequently policy-created (e.g., semiconductors)
- •Trade can become ‘goods for assets’ under persistent deficits
- •Long-run welfare is less obvious when deficits accumulate and assets are sold/issued
- 8:56 – 10:22
“Are we becoming China?” Tariffs and industrial strategy as American tradition
Asked whether his policy agenda mimics China, Cass argues many of these tools were historically American. He frames the shift as adapting to China’s existence rather than copying its political model.
- •China doing something doesn’t automatically make it wrong
- •High tariffs and protection were part of historic US development strategy
- •Industrial policy and immigration restriction are framed as traditional tools
- •Policy must account for China’s strategy rather than ignore it
- 10:22 – 11:47
Will Trump’s tariffs revive manufacturing? Timeline, mechanisms, and complementary policies
Cass predicts tariffs will raise manufacturing investment and output over a multi-year horizon, but stresses implementation lags. He argues success depends on stable, credible tariff commitments and complementary industrial policy and workforce development.
- •Cass expects effects over ‘a few years’ (investment decision + buildout time)
- •Tariffs aim to change capital allocation toward domestic production capacity
- •Credibility/stability of policy is essential for firms to invest
- •Complementary policies: industrial policy support and workforce pipelines
- 11:47 – 15:41
Short-term pain vs. long-term gain: supply-chain disruption and conflicting indicators
Smith argues current data show manufacturing weakening after major tariff announcements, consistent with supply-chain disruption in intermediate goods. Cass disputes the breadth of the downturn narrative and points to anecdotal reshoring/investment signals, emphasizing it’s too early to judge.
- •Smith cites contracting PMIs, shrinking orders, and weaker investment plans
- •Mechanism: tariffs disrupt intermediate inputs, raising costs and uncertainty
- •Cass disputes ‘all flashing red’ framing and highlights reshoring anecdotes (e.g., TSMC, pharma)
- •Core dispute: what should be expected in the first months vs. after several years
- 15:41 – 24:24
What counts as evidence? PMIs, employment, production, and the right evaluation window
The conversation turns into a methodological clash over which indicators matter and how fast they should respond. Smith treats PMIs as reliable leading indicators; Cass argues the relevant outcomes (employment/output) inherently lag because factories take years to build.
- •Smith: PMIs are widely used and correlate with later government statistics
- •Cass: employment/output won’t surge immediately because capacity must be built first
- •Debate over whether economists’ short-run predictions have been validated
- •Agreement that capital investment and construction are key leading indicators
- 24:24 – 27:56
What would change their minds? Investment, productivity, and the ‘testable’ milestones
Torenberg asks both guests what evidence would cause them to update their views. Cass focuses on sustained domestic capital investment and eventual manufacturing productivity gains; Smith says a clear resurgence in investment and factory construction would be convincing.
- •Cass’s milestones: capex response (1–3 years), then capacity/output/employment
- •Cass emphasizes productivity as the ultimate signal of a revitalized sector
- •Smith’s milestone: a renewed boom in manufacturing investment and factory construction
- •Both frame the debate as empirically testable over multi-year horizons
- 27:56 – 40:41
Industrial policy, workforce development, and the need for stable rules
Both agree tariffs alone are insufficient without industrial policy and skills pipelines. Cass criticizes tariff volatility and argues predictability and legislation (vs. executive churn) are necessary to induce investment; Smith highlights vocational training and capacity-building policies.
- •Industrial policy (e.g., CHIPS) as a major driver of recent factory construction
- •Workforce development and vocational education as binding constraints
- •Cass: stability and certainty of tariff regimes determine investment response
- •Shared view: a full reindustrialization strategy requires multiple policy levers
- 40:41 – 45:18
Tariffs as policy vs. tariffs as threat: strategic trade, bargaining, and credibility
Smith distinguishes between using tariffs as leverage (to change adversary behavior like currency policy) versus using tariffs as permanent protection. They debate whether threats are credible and whether carrying them out becomes self-harm, especially with allies.
- •Smith: tariffs can be a bargaining tool (e.g., to deter currency undervaluation)
- •Game theory logic: credible threats ideally avoid being used in equilibrium
- •Question of irrational actors and when ‘economic war’ logic dominates welfare
- •Cass: credibility requires willingness to impose tariffs, and China isn’t rule-following
- 45:18 – 1:07:53
Allies, scale economics, and trade balances: pooling markets vs. net-deficit politics
Smith argues the key to competing with China is scale—pooling markets with allies for higher volumes, lower costs, and specialization via product differentiation (Krugman-style models). Cass counters that allies also pursue export-heavy strategies that create persistent imbalances, raising questions about reciprocity and how to negotiate rebalancing.
- •Scale economies: larger markets lower unit costs and improve learning-by-doing
- •Argument for near-free trade with allies to match China’s scale advantages
- •Cass: key allies run large goods imbalances with the US relative to GDP
- •Debate over net vs. gross exports and whether trade expands total demand enough
- •Negotiation problem: what leverage the US should use to rebalance with allies
- 1:07:53 – 1:12:44
Baseline tariffs and closing positions: a permanent 10% floor vs. targeted constraints
Cass outlines a preferred steady-state: a predictable baseline tariff (around 10%) to tilt incentives toward domestic production and generate revenue. Smith presses on falsifiability—how long Cass would wait before conceding tariffs aren’t working—and Cass answers that investment response plus complementary policy follow-through are decisive.
- •Cass: baseline tariff can ‘skew the playing field’ toward domestic production
- •Predictability matters more than week-to-week tariff changes
- •Smith: prefers targeted tariffs (strategic sectors) rather than broad ones (e.g., clothes/toys)
- •Cass: would reassess after ~1–2 years without investment response, especially if workforce/industrial complements fail
