Taxes would definitely work, if there are politicians who campaign on those and get elected. The problem is that politicians more often than not represent the upper class. So they sell other ideas instead. This is why I'm not confident we'll be able to curb inequality via the democratic system. What we can do however is what we did the last time around - use our labor power. Use labor power to get much more of the profits, use both labor power and some of those profits to hire politicians to get those tax laws passed on top. Could it happen that we get some party to elect a leader who's the type of ideologue that gains popular support and passes such laws before labor power forces them to? Yes. I'd like that, it's easier. I don't think it's very likely though. Just look at the state of the NDP over the last decade.
