You re forgetting the bailouts, stimulus packages he pushed through congress. All in his first 3 weeks in office (which is quite an accomplishment even if you don't agree with him). IMO I think it is the best option considering the alternative from the other party, that has already proved that it doesn't work (even though some here on the forum might not recognize it because they seem to be in denial about that).
Peter Schiff Stimulus Bill Will Lead to "Unmitigated Disaster": Tech Ticker, Yahoo! Finance
A good thing!!??
Yeah a good thing, nobody will get extra taxes right now and almost everyone will get tax cuts + more job security. 95 % of the people are getting tax cuts, remember? This investment will be paid back with taxes after the recovery (probably even possible with the same tax levels).
Normally this can not do anything "wrong", it can only fail and then the effects will be less worse then if we did nothing ( but we will have lost money of course). It can't worsen the economy, because the government is giving people/companies work (what they don't have at the moment: demand) by spending and because the private sector doesn't invest the governments actions don't conflict with the actions of the private sector.
If I simplify the economy very much then it comes down to this:
Demand (spending consumers & investments companies) = going down very fast
Supply (companies) = following the demand -> going down very fast (stocks & Jobs)
So what happens with this stimulus (this is an example, I don't have actual numbers so I won't be able to calculate but I suspect the proportions are similar to this example):
+ Demand (spending/investments Government) - Demand (consumers & companies) = "?"
Supply (companies) = following "?"
The possibilities are (government actions seen over a timeframe of 1 to 2 years):
"?" (1) = going down fast (less fast, recovery between 2 and 5 years) Failure
"?" (2) = going down slowly (stabilizing : visibly slowing down and recovering after possibly between 1 and 3 years) Success
It is a risk, but it would be worse if we did nothing because then the risk would be even higher.
Option (3) without the bailout = possibly up to 10 years (depression) because of destruction of mayor companies, banks, ...
Speculation: Biden Himself got probably such a calculation (but then much more complicated of course) from the economic experts of the Obama government in which the outcome was 70 % for option "?" (2) Succes and 30 % for option "?" (1) Failure. That could be the reason why he said it publicly.
