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.
Oh yeah. I remember learning about this one. Living in America, I don’t think a lot of us are aware of Roma people, and thus don’t know it’s a racial slur.
I blame Notre Dame. That movie made me think it was more of like a job description like a traveling merchant. I didn’t know it referred to a group of people until I had internet.
