"Leaders" told everyone to stay home. People, largely, listened for a while. When the money ran out (or never existed to begin with) and no support came to sustain the situation but the messaging remained "stay at home" thats when people got mad and stopped listening.

Since the same leaders also said wear a mask, it went from "health experts trying to save lives" to "politicians trying to leave me destitute and homeless".

The US failed, as it always does, to provide for the needs of its citizens. So as the citizens usually do, they stopped listening. And in practice absolutely nobody gives a real shit - the people don't care and capital is eating future generations by the trillion. Everyones happy in the most perverted definition of happy.
