Sounds like learned helplessness. This is only allowed as long as the governed permit it.

Not every politician is reducible to a single, cliche hivemind. When the person lacks integrity and a record of telling the truth, it's unwise to believe they will keep all of their promises.

Trying to deduce general principles from many particular instances is not "learned helplessness". If one wants to understand a system, it's best not to delude oneself with myths, but to spell out the pattern that is confirmed by many observations. A strong myth that keeps the American people in their current state is the idea that the US has a democratic government at the federal level. Once they get over that myth, they might actually be able to make it true.
