That's just not true. The Haymarket Riot is widely taught in history classes. I don't think there's a single history class that covers the 20th century and fails to mention the Great Depression and the New Deal. They might not spend a lot of time on things like the Bonus Army, but you can't really cover the Great Depression without mentioning rebellions and unrest.

It's true that they like to talk a lot more about the genius of Henry Ford and give him credit for the 5 day work week, and not mention all the labour movements and strikes that led to the 8 hour day and 5 day week. But, it's more a matter of what's emphasized rather than outright censorship.

Besides, the whole founding of the US is framed as a rebellion against authority. They barely even mention that the founding fathers were almost all extremely rich nepo babies. The founding story of the US could be taught as a bunch of rich white men who deserved to lead because of their prowess as capitalists taking power from a distant king who was demanding a bailout due to his financial mismanagement. That would probably even be closer to the truth. But, it's framed as a bunch of plucky men taking power back for the people from an autocrat.

Not true I heard about the Whiskey Rebellion and Shays Rebellion at least once

I graduated high school in the late 90s in white christian suburbia USA. It's definitely unnerving how often I get to go down a rabbit hole about events that happened before I was born but are still new to me.

That's especially true when the "rebellion" is something other than war or occasionally civil rights. Anything related to labor or worker's rights just didn't come up.

But then I had to keep learning about the world from as many sources as possible, and instead of fulfilling my destiny to be an angry unwell rich republican, here I am on Lemmy and spending more time thinking about my family, hobbies, and farm chores than about work. I use Debian btw.
