It’s not correct to say that people only received $1200. Everyone qualified for that stimulus (depending on income thresholds, it was phased out for higher incomes), regardless of job loss.
Unemployed people receive an additional $600/week from the late-March COVID relief bill through July 31. There are additional measures to extend the duration of regular state unemployment. The combined benefits given to unemployed people are over $10K/person additional, on top of regular state unemployment.
Furthermore, many of the numbers you’re citing are in the form of loans or other non-spending activity. It’s not correct to suggest that we could have simply given that money to the people and arrived at the same budgetary outcome.
I don’t agree with the way all of the funds have been allocated, but suggesting that we could all have received $18K is disingenuous. Proper response should be targeted where needed, such as the unemployment measures and loans for businesses that were forced to close, not just distributed to everyone who kept their jobs and businesses.
