Government spending is how a Keynesian combats a recession. For perspective, though, look at this chart of government spending as a % of GDP. It has never gotten even close to 85% of GDP (https://fred.stlouisfed.org/graph/?g=8fX). Chamath claimed it was 85% of GDP growth, which is a different calculation, but looking at [this data](https://www.bea.gov/sites/default/files/2024-10/gdp3q24-adv....) from the past couple of years you can see that the claim is still incorrect.
