I agree with you about lumping all of capitalism's many forms under one name, but it's still the most commonly used term to describe right now. If I wrote for academics, I'd be more precise, but the average person understands capitalism.
Fascist Germany evolved from European capitalists aiding the pro-capitalism party after the Germans overthrew the Kaiser, and fascism and capitalism tend to go hand in hand.
I don't know why people insist the world's been primarily peaceful since WWII. The US upped the war ante, and we've been at war most of the 20th and 21st centuries. Maybe it's just normalized - I don't know, but it's a common belief.
If you're referring to Stalin and Mao, they employed state capitalism, and I've still not found any evidence of communism's destructive narrative. Every time a nation nationalizes resources to serve the public, the US invades and/or sanctions them to implement capitalism.
Regulated capitalism provides benefits, but limited government intervention is one of capitalism's pillars. When the US government radically altered capitalism during the financial crisis, we encountered a whole new disaster, and it's still destroying us.
And the wealth argument. Yes, capitalism provided wealth for some, but who exactly? We created a world that depends on wealth to buy basic needs, and we can't see the world any other way. The wealth discussion takes a lot of time to break down. If I get a chance, I'll write more about it because it requires a lot of details and info.
Thanks for the feedback. xo
