Destroying the American economy (i.e., capitalism) is ...
They may very well hurt the world’s economy but they will never “destroy” capitalism.
Capitalism (unlike Communism) works because it goes with human nature. A person’s labor has value if they don’t earn what they are worth they will do one of two things, stop working or enter the underground economy.
The great loser in all this will be governments tax revenue since the underground economy does not pay taxes (or fees).
(at least that is my take on how things work)
Your points are valid, of course, and “destruction” is hyperbole. The Democrat/Communist/Left Party is not capable of eliminating capitalism (although that is clearly their objective), but they can sure do damage to it in the minds of Americans who remain in an 18-month-long covid stupor. Cheers!
