The Cost of Space Exploration

Episode Summary

Executive Summary: The episode opens with a sponsorship read before pivoting to NASA’s Artemis/SLS moon program, arguing its massive cost, single-use design, and politics make it an inefficient legacy system shaped by congressional interests more than engineering optimality. The second half answers listener questions on inflation, taxes, monopoly models, and unions, emphasizing how macro policy, market structure, and labor power interact in shaping prices, wages, and inequality.

Main Topics: NASA’s SLS rocket and Artemis costs (Priority: 5/5): The hosts discuss the enormous development and launch costs of NASA’s Space Launch System, framing Artemis as years behind schedule and far over budget, with sustainability concerns around a $4 billion-per-launch system. Public pork-barrel politics vs. private space innovation (Priority: 5/5): Adam argues SLS reflects U.S. congressional politics—especially Alabama’s role—rather than cutting-edge space economics, while reusable private rockets represent a more cost-efficient path. Space, militarization, and the lunar economy (Priority: 4/5): The conversation links rocketry’s military origins to modern proposals like Space Force and a future lunar economy based on science, tourism, and mining, with private-public competition expected to intensify. Inflation and taxes as macroeconomic tools (Priority: 5/5): In the listener Q&A, Adam explains that progressive taxation could reduce inflation by lowering aggregate demand, but interest rates are used instead because they are faster and politically easier to adjust. Why economists still use perfect competition (Priority: 4/5): Adam explains that perfect competition models are useful as simplified benchmarks, but real economies are dominated by imperfect competition, monopolies, and oligopolies; cutting-edge economics already incorporates this. Union decline, wage pressure, and inflation (Priority: 5/5): The final question links weak union power to slower wage-price spirals today, contrasted with the 1970s; Adam argues inflation policy can indirectly weaken organizing efforts by easing pressure for wage bargaining.

Key Arguments: SLS is extremely expensive to build and launch, with development costs rising from an intended $18 billion to $23 billion, making it a legacy program rather than a modern, efficient rocket system. Reusable rockets, as pioneered by private firms like SpaceX, offer enormous cost savings compared with single-use systems and likely represent the future of heavy-lift spaceflight. The Artemis/SLS program survived because of U.S. political incentives—especially Senator Shelby’s influence and protection of NASA installations in Alabama—rather than because it was the best technical choice. NASA’s economic footprint is meaningful locally and through contractors, but it is not a major macroeconomic engine despite claims about job creation and multiplier effects. Raising taxes on the rich would also be disinflationary because high-income households account for a disproportionate share of spending and wealth; fiscal policy could, in theory, do what interest-rate hikes do more bluntly. Central banks prefer interest rates over tax changes because rates can be adjusted quickly, whereas tax policy is slow and politically difficult in Congress. Perfect competition is taught because it delivers elegant mathematical results, but it is a poor description of modern markets dominated by pricing power, scale economies, regulation, and oligopoly. Union strength matters for inflation dynamics: in the 1970s stronger labor could trigger wage-price spirals, while today weaker unions mean wage growth is often lagging inflation rather than driving it. Anti-inflation policy can have an indirect political effect by reducing the conditions that encourage labor organizing, which central bankers may understand even if they do not say so openly. The moon economy is being imagined as extractive and commercially profitable, with actors already planning settlements, power systems, 3D-printed structures, and resource extraction, suggesting a new frontier of geopolitical and economic competition.

Pivotal Quotes: "This is the kind of direction that Elon Musk's team has gone in. It saves an enormous amount of cost if you can recycle key components." — Adam Tooze: On why reusable rockets are more efficient than NASA’s single-use SLS "This is in no way a project shaped by the latest thinking about rocket technology or space travel or least cost." — Adam Tooze: On the political origins and inefficiency of the SLS program "Perfect competition models are one of the most commonly taught sort of workhorse models in microeconomics courses." — Adam Tooze: Explaining why simplified models remain central despite real-world monopolies and oligopolies

Implications: The episode suggests space policy is as much about politics and industrial power as exploration, while macro policy debates increasingly hinge on distribution, labor power, and the limits of textbook economics. Future moon development may be commercial, militarized, and highly contested.
