You make an interesting point, but there's an issue that significant resources are put into making sure that people do not understand economics, law and geopolitics properly. Economics is particular egregious in that the academic discipline is, for the most part, complete horseshit, and popular economics is a bastardised version of that. Geopolitics is also filtered heavily through whatever lens one views it.

>More than 50% of American voters voted for him. I am having a difficult time to believe that 50%+ of the US are economically oppressed that had no choice but to vote for Trump.

I think it's important to be accurate with this stuff. 49.8% of voters voted for Trump, approximately 32% of eligible voters voted for him, and roughly 23% of the population voted for him. Don't discount apathy, disillusionment, and disenfranchisement in all this.

Inequality is very different to no prospects, or no hope.

Yes but the cause was not American. And USA was pretty reluctant to be dragged in (not Roosevelt but the voters).

I am just pointing out that you can make up any list in hindsight and make it look like Nostradamus prophecies.

Where is french revolution or the great war in that list?

Fully agree. My kids consider(ed) history to be very boring, other than when I teach them about it. I thought I disliked history after coming out of high school because the classes were always so excruciatingly boring and felt so irrelevant to anything "modern day." As I went through my early career I found myself constantly wondering "why is X that way?" Personal research including reading books written by historians who actually tell the story and also describe the many various links between events, and especially the "other side" of many of the issues (that's particularly fascinating regarding the USA "founding fathers" as they were far from a cohesive single-minded unit as presented in most history classes) many things started to click. When I've taught my kids about history using the same approach, especially zeroing in on the real fascinating aspects of it, they still don't love history but they have a strong appreciation for it.

By way of example, "the founding fathers were Christians" is a classic oft-repeated phrase I continually hear, to which I love talking about Thomas Paine, Thomas Jefferson, and Benjamin Franklin, all of whom were clearly agnostic (at the time, they were "Deist" which was essentially equivalent to "agnostic" nowadays). Thomas Paine's phenomenal book "The Age of Reason" was utterly mind-blowing and extremely radical at the time, receiving widespread banning and igniting firestorms in the culture. It's still a great read today! Especially fascinating when you consider this was many decades before Darwin would provide one of the most important scientific explanations that massively shrunk the area for God of the Gaps.

I agree with you, but I would also add that real history is also typically much more uncomfortable, for nearly everyone. It can also be legitimately controversial as there's truly a lot that we don't really know, particularly around people's motiviations and sometimes true beliefs. For example it was common practice for people to burn any letters that didn't reinforce or support what they wanted history to remember. It takes someone with real dedication towards separating themselves emotionally from the topic to attempt an accurate portrayal, and that is a rare quality indeed. Certainly not a quality widespread enough to be present in every middle school and high school history teacher (though there are some excellent ones out there).

Some examples of the discomfort: to many white people now the history of slavery and racism is deeply uncomfortable. It's not even difficult to find hard evidence of such as many racist attitudes persisted well into the era of recordings and have been immortalized in movies and TV shows. I suspect a big part of that is the recency effect since we're still living with many follow-on effects of the practice even if we don't practice it actively anymore.

Much less talked about though is the history of racism and slavery among nearly all people at different times. For example a large majority of the black slaves that were sold to Europeans (including the Europeans living in the Americas) were originally enslaved by other black Africans and sold to the slave traders. Not all the slaves were sold either. To be fair the Spanish (at least in first half of the new world exploration) didn't have much of a problem doing the enslaving themselves as they routinely enslaved native people's after conquering them. We can also go back millenia and see the same behavior. Greeks, Romans, Persians, pretty much everybody had their slaves for as far back as history is recorded (and surely much, much farther).

We like to think we are enlightened nowadays, but I think history really demonstrates that as humans we are almost universally inclined toward enslaving other humans. Hopefully we're irreversibly past that now and well on our path to the Star Trek society, but even if that is the case it doesn't make the history any more comfortable.
