Who's gonna pay for this mess? Certainly not the 15% of American's who find themselves recently unemployed. Certainly not the wealthy. They're too busy managing another vast transfer of wealth via Federal Reserve money printing.
So who?
If anything, this pandemic exposed the shortcomings of the system, with no safety nets or contingency plans of any kind, letting wealthy corporations get away with murder, while the working poor can't afford healthcare or get denied coverage.
I'm not holding my breath that after experiencing it, we've learned anything
There always seems to be plenty of money for bailing banks and the Wall Street but never for creating a safety net for situations like this.
So to answer your question, I don't know where the money will come from, I just know that as the richest country in the world, there's plenty of money lying around.
Nothing will happen until we sharpen our pitchforks, stop voting against our own interests and thinking that having a safety net equals socialism.
