This is an underrated point because the U.S. failure to rein in the excesses of the ultra-wealthy is not just impacting our domestic politics but actually the politics of every country on earth. Imagine if Jack Ma had eventually personally intervened in U.S. congressional elections? That's pretty much exactly what U.S. oligarchs do to other countries regularly.
You are using a lot of obfuscated and loaded language. What, specifically, are the "excesses of the ultra-wealthy" that need to be reigned in? What do you mean by "personally intervened in U.S. congressional relations"?
