Interestingly, if the US stopped spending you’d need the top 17 remaining countries to double their spending to absorb the American science industry. Doubling is a tall order and seventeen is a large number. Most likely fewer scientists will find employment in government funded academia if this came to be.
certainly true, but if another currency is also the reserve currency, that country/group will be spending all that money
