They just refuse to believe it's not sustainable, and if you don't agree with them. Then they fire you if you worked for them, if you were a politician they found a competitor to knock you out of office and say the lies they wanted to hear.

They've spent decades and billions of bribes to make sure there were two options, and both would do what billionaires tell them to. But the billionaires no longer control both parties.

Hell, they arguably don't control either, trump just usually agrees with them on his own.
