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.
This is so so widespread that I am very curious about it.
One hypothesis I have is that people believe their sexual inclinations are completely separate from social and cultural influence. That the sexual preferences are somehow innate or beyond influence--even though they clearly are heavily influenced.
At the very least fucking keep it to yourself that you don't date black women or prefer dating east asian women you weirdo agghhh
