The trouble is that the inequality story is a complete mischaracterization of the problem and it's very misleading about what the prospective solutions are. It leads people to believe that the issue is with John McCain owning houses across multiple states, when the actual problem is with the Koch Brothers owning Senators across multiple states.
And what's the solution? Everybody says "tax the rich." The problem is that income taxes doesn't cause their wealth to decrease, they at best cause it to increase less rapidly. In practice they do nothing (or worse than nothing) because the biggest companies don't pay them anyway, and it creates a large competitive disadvantage for companies not large enough to engage in international tax avoidance, which makes the problem even worse.
Meanwhile any money you manage to raise you can't spend until you first fight against a bunch of "domestic companies creating American jobs" who want to use it to fund Deep Water Horizon 2.0 or studies denying climate change or supply attack helicopters to the North Dakota state police, because aforementioned billionaires still have a thousand times more money than you with which to lobby Congress.
The only way to fix any of it is to shut down K Street. Obviously that's a chicken and egg problem, because K Street is in a good position to protect itself, but if that's not your end game then you might as well stay home.
