They don't teach it how they should in schools and they probably never will. I had to do a project recently looking at different US events from a money perspective.
But US slavery, as bad as it was, was inevitable. The truth is that within the group of British settlers that came to America, there were some real, self-entitled "brats" among them, with real dark sides. The worst of the worst from Britain. These were some of the most hypocritical people in our history. The mindset they had carried on throughout history (mostly in the south) and revealed itself in various events, including slavery, through the the expansion of American capitalism.
The sad thing is that slavery wasn't just simply about hatred. It was about cheating the labor markets and maximizing profits. The racism was just icing on the cake.
Our history is kind of funny you know. Especially looking at how things are today too.
Example our immigration problem. A lot of us are very restrictive when it comes to access to our country, too bad Mexico didn't feel the same way when they allowed American settlers to share land, they might have more land than they do.The first immigrant contact between them was actually Americans settling into Mexico, which Mexico allowed them to do right after gaining their independence. Even gave them citizenship. But we refused to learn their language (funny how we make them learn English here though right), adapt to their culture, and even to sell from their ports. We did pick up Catholicism from them (though we don't give them credit in our history books). And to think Mexico was even willing to allow us to keep our slaves despite it being illegal. Just bending all the rules for us. Similar to what the Native Americans did when they tried to share land with us too only to be taken advantage of via"manifest destiny" (self-entitlement).
Fast forward after taking the land, we assimilate the Mexicans into our culture (what we refused to do), made their women learn to cook, clean, sew, etc (thus the mexican maid stereotype, remember "Consuela" from Family Guy?) and take what property they did own when it was still Mexican territory. But the biggest thing we did was allow the men to come work in agriculture, mostly cotton farming. Thus we suddenly had a bunch of Mexicans in the country, and this was fine as long we were getting cheap labor out of it.
But then we messed up our economy and the Great Depression hit. Suddenly, Mexicans are taking our jobs (sound familiar?) and immigration became a problem. We started deporting them. Until we had a war to fight and needed cheap labor for infrastructure while our men went and fought, so we brought them back, until we didn't need them, them we tried to kick them out again, and the rest is err....history.
And it doesn't stop there. But it always comes back to greed, self-entitlement, and capitalism. And from the first settlers right on through the days of the south, you can see the similarities. It wasn't all, but just like today, some white people are worse than others when it comes to minorities. Just how it's always been historically. But thank god they aren't as bad as the ones from history. They were the real OGs lol. Basically took your shit and called it freedom haha.
