as I said I don't think checking historical trends is excuse for current policy.
> Seeing as Trump is a Republican, and that his spending and economy were on brand for the Republican party, I see no reason to assume covid was the sole cause
first two years of his presidency deficit was relatively low
> Given that the US economy has recovered from covid dramatically better than the economies of all other major nations, I am not inclined to assume that the US economy is currently in poor hands. On the contrary, it sure seems to be in the best hands that exist anywhere in the world.
this is a loaded question. Recovery was in expense of inflation, rise of debt. One would need to do some quantitative calculation to see if current situation is result of actual policies (and which policies: Trump's or Biden's), or just economy is flexible itself and if result could be better and if spendings were justified(or went to real estate market and stocks).
