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.
It's also abysmally ignorant. Roma have been in Europe for centuries, but they originally migrated from India. It was assumed by medieval Europeans that they were from Egypt, because Egypt is in the Bible, and India isn't, so they all knew about Egypt. So they called the the G-slur as a proxy of "Egyptian"
For centuries the word used in Danish for Romas and travellers (why be precise about who we're talking about?) was "Tatars". People didn't know shit about where the Romas came from but Crimea sounded like an exotic place so why not pretend that this is where these exotic people came from? An example of the use of this world is the 1665 legal code that bans "Jews and Tatars" from the country.
