What do you think is accurate? Almost everything he says is just speculation and conjecture where he gives no evidence, just his opinion.
Left-right politics is incredibly subjective.
Motivations behind actions is conjecture.
The stuff about schools, news, and corporate interests is all speculation where he offers no evidence, I could easily say the opposite with no evidence and it'd be just as "accurate" as you put it.
Communism has existed, this is as dumb as saying capitalism doesn't exist because public services/taxes still exist in capitalist countries. So many times you'll run into people who think whatever their dream government is just hasn't been implemented correctly before, but it's revisionist to deny the failed attempts as that form of economic governing. Just because you don't like how the communist governments were ran (corruption, abuse, elitism) doesn't make them less communist, it just shows the flaws in implementing such a system. source
The japan surrendering is bullshit, notice how all the opinions listed are from americans speculation about what was going to happen and nothing from japanese officials? That's because in 1945 when japan sent Prince Konoye as an emissary to the Soviet Union to open discussions they listed no surrender options, and no terms in which they considered peace. source
American slavery did end, the link sends you to a book where the author talks about people who worked for a company then end up owing the company more than they're making, effectively being "slaves by another name" with some key differences, you could leave whenever the fuck you wanted, they didn't have the right to beat you, they didn't have the right to kill you for learning to read, etc. The two concepts only share one common thread, that you worked and ended up with no money for your work. But that's where it stops, real slavery was much, much worse. read up on wage-slavery
The vast majority of his comment is legit conspiracy, thinking that a group of people is conspiring to act for a dubious goal in secret. It's the definition of conspiracy.
