No it's just what he implied in his soundbite. Imagine being a rich person in that room hearing Biden say "and nothing would fundamentally change" and think he's literally only talking about a number in your bank account and that he means everything else will fundamentally change. He was at some donor event probably full of rich ghouls. Your liberalism is on full display amigo.

Here's context:

"Biden told donors at an event at the Carlyle Hotel in Manhattan on Tuesday evening that he would not “demonize” the rich and promised that “no one’s standard of living will change, nothing would fundamentally change,”" - Salon.com.

He literally says no one's standard of living will change.
