> Then you get sad, because you realize there is no way to get actual representation for the issues you care about other than to run yourself, but if you ran explicitly to challenge those in power, those in power would fund your opposition. So then you realize that it's hard to get into power without expressing loyalty to those who grant power, and then you have a cogent explanation for why things are the way they are.
Can you say Bernie is in power? I think he proves my point, especially in regards to the presidential primaries, or maybe that's the point you're making.
He was giving a speech to some super privileged college kids not too long ago when one of them asked something like "why should we work against a system that benefits us" and he said change likely isn't going to come from the government/rich kids so he's working on organizing unions because that's where meaningful change will come from.
Solidarity/Collective bargaining is how you challenge power.
For a practical example, see Bernie.
