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 pretty much how it works worldwide. Living in The Empire™ grants you that benefit. "The power of a US passport" is very well known. Every country could use American tourist money. It is absolutely another neo-colonial sort of relationship. I saw a documentary that shows that Jamaicans (or another Caribbean country) have a harder time getting into Jamaica than Americans do.
At a lot of airports (eg Singapore) there is an expedited immigration check for 🇪🇺 / 🇺🇸 .
Quite literally
