We have an oligarchy now, bought and paid for, through buying politicians with unlimited funds, mega-corporations controlling the media, and by other means.
Classical oligarchs are against public works (infrastructure spending); they want to keep all the money they can get their hands on. They support voter suppression — why let the unwashed masses mess up how they want government to work by voting? They are against public education; an educated populace is a threat to their reign. They could care less whether the labor force as a whole is getting less and less — all the better for their personal profits.
Depressions are a means to getting a cheaper labor force. The same goes for universal health care, an expense keeping the unwashed alive at great cost to the bottom line. Climate change is something interfering with the immediate business as usual, especially for the fossil fuel industry.
Those who most perfectly support this oligarchy are the Republicans. Kick them all out! Only then can we dig ourselves out of the mess we are in. By controlling even one branch of government they clog up its functioning. We do better economically under the Democrats anyway.
