You’re blatantly misquoting the person you’re replying to.

In what way. You would call being 18th in income mobility "tremendous?" I wouldn't.

Why not?

For you, it seems that "tremendous" means best in class. Where is the cutoff, 1st, 3rd, top 10?

For others, being in the top 10 percent of 195+ countries is quite significant. For the average person in the rest of the world, being in the US would provide a significant and meaningful increase in their economic mobility.
