I think everyone feels most of these, or at least says they do. If anything, all the head nodding in this thread is a nice example of a Dunning-Kruger effect.

Impossible to say; we've never been in a situation like this before.

Traditionally, a "reboot" happens when things get bad enough that people feel - rationally - that the risks and costs involved with attempting to force a solution are worth it. Part of the risk is the risk that others won't help, so once a real movement gets started it tends to be somewhat explosive.

However, thanks mostly to technology, things have gotten better on an absolute level even as inequalities have gotten larger. "A rising tide floats all boat" isn't true, but it's not entirely false either. Today, there's no real risk of starving to death in the USA, not for 99% of the population.

Time will tell if relative differences are enough. The situation is quite unprecedented.

There's a line in the live version I have of Alice's Restaurant that your comment reminds me of. It comes after the usual:

And if three people do it, three, can you imagine, three people walking in, singin’ a bar of Alice’s Restaurant and walking out? They may think it’s an organization. And can you imagine 50 people a day, I said 50 people a day walking in, singin’ a bar of Alice’s Restaurant and walking out? Then, friends, they may think it’s a movement.

He says something along the lines of "And most of them would be too young to know what a movement was."

I think step 1 should be "reduce the influence of money on electoral outcomes." That would significantly lower the bar to putting pragmatic and thoughtful humans into positions of power without leaving them chained to the well-funded interests that helped put them there.

The problem is, I don't really know HOW to do that.
