The theory of evolution goes both ways.

Most parasites evolved from more complex species. They gradually lose the ability to produce for themselves what they are taking from their hosts.

Dodder has lost the ability to photosynthesize it's own food. It sucks its food out of others.

The similarity to Trump and his uber-wealthy supporters is pretty clear, don't you think?

As workers become more productive, the uber-wealthy take all the profits and then some, hording the money in ways that do not improve the lives of those who actually created the wealth.
