Capitalism is not only "the concept of goods traded for legal tender", it is an ideology that wealth accumulation is the one true moral good to strive for above all else, no matter who or what you have to exploit for it. It is a system where power and capital are one and the same.
Imperialism is the highest stage of capitalism, fascism is imperialism turned inwards. It's a corporate capture of government to remove all obstacles for wealth accumulation, private growth at the expense of the working class using the out-group as a scapegoat. It's not only a really bad guy getting into power, it is the natural progression of capitalism.
Theres hardly ever a time in the past better than this decade in the USA.
This is laughably false. Holy shit you're brainwashed.
If anything you suggested worked, we wouldn't be here. We have had all of that in the past, and it didn't solve the core problem that allowed all of it to then be taken away.
It's a great thought experiment, but it's not a plan and it doesn't help anyone who was already struggling before the last decade.
