Sure. Fine. It's still so reductive as to be nearly useless. Try living in low tax, libertarian havens. There isn't much social mobility. You're born into wealth or you're not. Money and power flow up the (very short) pyramid forever.
One must tax the rich heavily because otherwise their money will just snowball until there's little left for anyone else. Cute phrases too often reinforce that reality.
Or since the middle class constitutes the majority of citizens, "No country has ever taxed *the majority* into greatness"?
