I would also add that the capitalist class loves to promote the idea if America as the greatest nation on earth because that storyline benefits them. They’ve already won the game and are benefiting from our current system. They don’t want it to change.
If we admit we have shortcomings–large gap in wealth equality, lack of accessible and affordible health services, piss poor public transportation, unaffordable child care paired with living costs so large 2 incomes are required, poor school funding, pervasive gun violence, and Policing that emphasizes violence, just to name a few-- then we are also acknowedging that we have to change things. Why would those who greatly benefit from our current system want change?
