Things that are so obvious and ingrained that no one even thinks about them.
Here’s a few:
All US americans can go to Mexico EASILY. You’re supposed to have a passport but you don’t even need one (for car/foot crossing). Versus, it’s really hard for Mexicans, who aren’t wealthy, to secure a VISA to enter the US. I’m sure there are corollaries in other geo-regions.
Another one is wealthy countries having access to vaccines far ahead of “poor” countries.
In US, we might pay lip service to equal child-hood education but most of the funding pulls from local taxes so some kids might receive ~$10000 in spending while another receives $2000. I’m not looking it up at the moment, but I’m SURE there are strong racial stratas.
That reminded me of a really odd 8th grade social studies moment. I'm Canadian and the teacher was talking about our low birth rates leading to an aging population, and he concluded that we should try to take in more immigrants to make up for the gap. Dude was a passionate lib that said 'democracy' in italics with a hand gesture (even funnier cause it was in French and he's Acadian descent, if you know the accent and speak French you'll know, if not I can't really get you there in text). We did a mock election on the day Harper got in, communists got 10% of the votes cause 3 of us voted for them.
My class (5th grade social studies) did the same thing when Harper was elected, except the cons won in a landslide since our teacher was an extreme right wing borderline libertarian guy who taught the class "conservatism is when you keep all the money you make, and liberalism is when you give it to the government in taxes, and the more taxes you pay the more liberal it gets". I'll admit I fell for that completely wrong explanation (in my defense I was 12) and "voted" conservative, but thank god I got my shit sorted out throughout highschool and into university
Cons can't even get a riding around here. Until you're out if the city, then it's all theirs
