I work with a young school so the experiences are not quite there yet for me personally. Sudbury Valley School did do a study of its graduates at one point and found that they led very satisfactory lives embracing challenges everywhere:

Our first graduate wanted to become a pastry chef and upon graduating our school, apprenticed to become one and is now a pastry chef at a well-respected restaurant. Our only other graduate just graduated from the college of his choice so it is a bit early for that one. From SVS, of recent fame is Laura Poitras, of Citizenfour.
My impression is that they embrace life with eyes wide open. If they happen to work for a bad outfit, they will understand why they are there (need the money, perhaps) and be open to moving on. They keep their power, always carrying around a memory of this accepting community in their hearts, motivated to take on challenges in their lives.
I am sure there are good stories and bad stories amongst the alumni, as with any group. But I would be willing to bet that the spark of living in the moment is almost universally present in all of the ones that attended a Sudbury school for most of their 5-18 years.
As for politics, a person can have a lot of power by taking actions, organizing, doing the hard work of establishing a movement. They learn at our school, presumably, that while voting is important, it is not nearly as important as being actively involved in the community, in talking with people, in making the connections that lead to results. Even bad bosses can be politicked for is not a bad boss just someone who is suffering and could use a helping hand?
I susepct your real question, and it is quite telling about our society, is "If you were going to end up a slave, would you rather have some freedom first or not?"
