Your critique of my post is valid and I agree with it, but I'm not sure my ultimate point is diminished. From what I've read, wealth and income mobility are correlated, if over longer timelines. Finding good statistics on wealth mobility over time on a global scale is hard, but I've yet to see any reason to believe they don't correlate with income mobility. And it makes sense if you look at the tippy top of the wealthy as an illustration: In nominal dollars, Bezos is less wealthy than Walton was less wealthy than Rockefeller, and Bezos is a major beneficiary of globalization. Rockefeller had an outsized influence on American politics because his wealth was chiefly American. Bezos, on the other hand, to hold his wealth incumbency needs to influence politics in the U.S., Canada, Mexico, the UK, the EU, Japan and China. Globalization definitely allows the rich to reach newer heights, but it also diffuses their influence and spreads their power thin.
