People assume that high earners will ALWAYS be high earners, but plenty of rich people have lost everything, and most of the ones I know are working very hard to avoid becoming poor.
Democrats keep trying to make the case that when you let rich people keep more of their money, they don't really use it to create jobs. What nonsense! What do they think they do with it -- keep it under a mattress? Unless they do, WHATEVER a rich person does with his money -- invest or spend -- creates jobs. If they spend it on a yacht, the boatbuilder hires workers. Even if they just put it in a bank, it is invested in some kind of enterprise.
If the government takes it on the pretext of "investing" it in green jobs or whatever, it's usually wasted.
