So with your 20/20 vision and your ability to see into the future what was the exact dollar amount at the time that you thought should be enough to stop a total meltdown of the US economy? Using logic and reason how did you come to the exact dollar amount that would emotionally appease investors and business providing them with enough "investor confidence"?

The timescale you are looking at is very small. The federal reserve has a dual mandate to have maximum employment and stable prices. What would have happened on a longer timeframe to employment and prices if every other country effectively backstopped their economy but the USA didn't?

It's like you don't know why the fed even came to exist or have any knowledge about the great depression or just fail to recognize how catastrophic that the pandemic was to the USA economy or the world economy as a whole.
