I've read about what was pushed in Southlake, Texas and other localities. It's terrible stuff whether your kid is white or black. It's not critical thinking. It's injecting racial assumptions about institutions and people (against facts and evidence) into the curriculum. It's the opposite of the positive themes of the civil rights movement. I wouldn't want it from David Duke, and I don't want it from Ibram X Kendi. It's corrupt, and some facets of it likely violate the 14th Amendment and civil rights legislation that was crafted back when racial equality was the goal and intentions were better. They are considering bringing it into DoDEA, and if they do, my kid will be gone. We'll find a private British school, or I'll homeschool him.
The problem with this meme is that it presumes a false equivalence. The people laboring in medieval had basically no upward mobility. People in the United States largely do. How many in medieval Europe had access to free education, scholarship funds, and credit to allow them to go to college? How easily could one start his own business?
Furthermore, though I have my criticisms of some of the richest in America and would stipulate that they've all done sleazy things at times, they are not like the wealthy in medieval Europe, who were wealthy largely because of who they were and what families they were born into. (In other words, they were wealthy for somewhat similar reasons that people in socialist countries are wealthy.) Guys like Bezos, Zuckerberg, and Gates had to do very big things to become billionaires. It wasn't just handed to them. Starting Amazon, Facebook, and Microsoft and guiding them into being global giants is a big deal, and at times the government actively fought them. They did have to work hard and undoubtedly struggled at times.
Hell, look at pictures of Bill Gates as a kid. Think that dude didn't get his lunch money stolen more often than not? Lol.
