I would be interested in where they get 100th in discrimination
Other countries might be ethnically diverse but not really racially. The US is by a wide margin the most racially diverse country in the world I feel like (no numbers to back that up). We’re by no means perfect when it comes to demographic harmony but 100th feels like an intentionally bad ranking
That number does seem a bit laughable

Here's the scorecard. I think the hiccup is to be able to separate causation and correlation. I think the best way to think about this is, the US is the richest, most powerful nation in the world, set on top of a failed state. Our social welfare programs are designed to incentivize stagnation among the lowest classes, as opposed to incentivizing social mobility. I think this is where the stuff from hillbilly elegy merges with the situation of urban poverty. So you combine the lack of social mobility with past laws that deliberately kept the black population impoverished, and you have the perpetual underclass.
Then of course, access to education, healthcare and housing is predicated on ability to pay and access to credit, which then again continues the lack of generational mobility. And while the US doesn't explicitly imprison and prosecute minority populations, the incarceration rates would indicate that something is broken, and whether overt or not, it would imply discriminatory practices.
I am also not sure what the "100" means here. I would agree that it is hard to find 100 countries clearly better than the US as they all have flaws. But overall the US is 28, and I don't think that's preposterous.
