There are....less beneficial and more destructive means to make money. Not all financial elites are evil, of course, but they do act for profit opposed to benefiting the human condition.

Big Pharma overpricing medicines and frowning upon natural remedies (or creating false "studies" that deter people from trying); there are no profits if people knew they could grow there own medicine in their backyard.

energy producers (oil mainly) keeping free energy capabilities (zero point generators, Keshe foundation systems) from the people. There is no profit in an cheap, renewable energy source.

Ignorance is the most profitable resource known to man.
