It has annoyed me for a long time that what happens in the US affects the rest of the world, but we (as in the rest of the world) have no vote and no say in the matter.

The US world view is summarized in Blinken's "if you are not at the table, you are on the menu".

The whites are at the table, the global south is on the menu, (and on the floor, looking for crumbs).

Although, in the end, the average white is also struggling day to day and worried about paying the debts, affording food and keeping a job. As long as there are 50 types of toothbrushes on the supermarket shelves, McDonalds is open and the kids aren't screaming, why care about the next town, let alone the jungle in the global south?
