All true but I think Trump is blowing the wad prematurely on this. This is not a pandemic. I get we're trying to prevent one, but even the worst case numbers being thrown around isn't a pandemic, it's a more aggressive death toll from a new virus. Tragic yes, pandemic no. Now if that number of deaths prediction was ten fold, then yes, full court press is warranted.How much was Bush's war, 3 trillion? Difficult to quantify the economic impact from that spending & squandered budget.
So far Trump's promised to throw 1.5 trillion at this problem in QE (without accounting for what's already been spent). The GDP impact will likely be easier to quantify than Bush's war however. It'd have probably been cheaper to have kept Obama's pandemic response program in place.
