I still feel one's voice can be heard when one gets involved in the Local Governmental workings, but the money and influence required to affect Federal workings is beyond most individuals and groups.
IMO, to reach the upper levels of Government a politician must cut so many deals and accept so much lobbyists money. I think 95% would betray their most cherished principles if it meant being re-elected.
Also, I think there may be a fundamental flaw in awaiting for the "right" people. It's been 2500 years since Plato pinned for the Philosopher-King who would be an enlightened ruler. The kind of top-down leadership doesn't work for the majority of people. Top-down socialism doesn't work, "trickle-down" economics doesn't work, Representatives working for the so-called "common good" or the "general will" always end up ignoring the majority.
The education issue is an important one. Education today was crafted in order to keep the divisions existed in American society in place. This isn't a meritocracy. Sure an occasional plebe is raised up out of his position, usually sports stars, great inventors or entertainers. Which is why they speak out often against the current system. But those Horatio Alger stories are more akin to the lottery than the American Dream. It's used to keep the "lesser" classes in check by reinforcing the if I don't succeed it's due to my inherent "wrongness" and lack of hard work and not due to any faults in the system.
Getting back to public education, it was purposefully designed to make most citizens productive cogs for in industry, government or the military. To be used up in labor or war and discarded once broken. Attempts have been made to alleviate this by Government and Unions to force disability pay onto Corporations and the creation of Social Security. However, Government bureaucrats even today cite the damaged cogs as a drain on the Government David S. Chu:

Education also works hard to instill respect and awe for Government and authority.
Why is the Congress in such an opulent building? Why all the pomp and circumstance and the titles of Honorable Congressman So & So? To overawe the masses. To make them equate those who should be working for us and at our behest as those who rule and "Decider" things for us.
Anyway, I'm going to vote Democratic (Tammy Duckworth) and I hope the Dems take the house and Senate but the system won't change.
