Yeah this ignores at least three things:

1. Most people do not derive even a fraction of their income from interest on wealth.

2. Earning income from interest on wealth requires zero effort. That isn't true for salaries.

3. Income and wealth are totally different things. You can find a way to equate them in one contrived example but there are so many other factors involved in the real world.

Billionaires gonna billionaire.
