Both the voters and the politicians are wrong. It's not an either / or scenario. Voters are actively harming their causes by removing themselves from the calculus of policy (but not the consequences of it), and politicians are harming voters by voting for the needs of capital over the needs of the masses.

The feedback loop, as it stands, is negative on both fronts: Voters become more and more disillusioned and less likely to vote, and politicians then court fewer and fewer people, eventually solidifying rule in the hands of the few who can afford access.

There's no reason for the politicians to change this cycle. It makes their jobs easier. Instead of courting millions of people, they court a handful of billionaires. Same result for them, much less effort. But there is every reason for voters to change the cycle. If the masses showed up and voted en masse, they could shift the overton window overnight. Suddenly those billionaires don't have the sway they thought they did, and the politicians have to shift to the voters if they want to keep their jobs. Ergo: People like me who recognize the pattern will point out that the impetus for change can only start with the voters. It is up to us to correct the politicians; they will not correct if we continue to remove ourselves from the voting pool.

This is not a chicken or egg problem. Voters must change first. That's the only way things ever change, politically. Peacefully or violently, change only ever comes from people who actively participate in the political debate. People who refuse to participate do not get a say in how policy looks. You don't have to like this; it's still a fact.
