US government funding of science isn’t a net cost due to taxes on the long term economic productivity that results. This is unlike say corn subsidies which not only reduce economic efficiency but also have direct negative heath impacts furthering the harm. Medicare spending is problematic because it’s consumptive, but there’s ways to minimize the expense without massively reducing care. The VA for example dramaticall…
> US government funding of science isn’t a net cost due to taxes on the long term economic productivity that results. There's an assumption here that deserves some closer examination. If we are taking this as a justification for federal science spending, we would have to also support a policy of awarding research grants on the basis of expected long term return on investment, which is not the criteria applied now.

The PageRank algorithm which led to Google was funded in part by an NSF grant on Digital Libraries. The ROI on that single invention just from taxes, jobs, and increased productivity likely exceeds NSF's annual budget. DataBricks and Duolingo are also based in part on NSF research.
Yeah, the system is imperfect, as all human-oriented systems are, but for the most part it works pretty well in practice and has been a linchpin in the US economic growth and national security.
