My question to you is why do you choose to prioritize that problem?

Yes, $70 million to the execs while many earn minimum wage sure does sound awful. But like OP says, even if you achieved resounding success in eliminating this inequality, it translates to a $32/yr raise. That rounds down to zero in terms of improvement in prosperity.

Isn't prosperity of the rest what we really ought to care about? It seems an awfully lot like focusing on the cosmetically ugliest problem that doesn't really move the needle.
