A better angle might be that currently in the US capitalism is rarely actually scrutinized for the disadvantages it does have. Capitalism is almost synonymous with America and people often see critiques of capitalism as an attack on the nation itself, even though most of them don't actually know the principles or characteristics of capitalism.

It goes the other way too where people automatically think that characteristics of America are capitalist

As an example a majority of Americans probably think that American politics and democracy is part of capitalism, or that the economy is pure capitalism.

If people were more willing to critically evaluate capitalism without feeling attacked it could increase support for more worker friendly policies that are generally socialist in nature while still having a capitalistic foundation.
