I doubt the spending will be anywhere near that high, but you can expect fresh stock market highs for the next several years, as inflation re-asserts itself. That’s why stock markets go up during Democrat administrations. The dollar’s value goes down, so prices adjust upwards - not just of goods and services, but of long-term assets like stocks and real property. Anyone currently holding long term bonds, however is due for a haircut, since interest rates are about to go up.
