I also feel the disenfranchisement that you talk about. I think non-electoral civic engagement is also an important part. I try to write my representatives on some issues. It seems largely futile, but often times you get a more detailed response from them than you see I'm the media. I also try to right the wrongs I encounter in my community. For example, a police department was wrongly stating that a specific summary offense was a misdemeanor and I was able to correct that. I also encountered a state trooper that was doing things that violate civil rights, like lying to a judge. I filed a complaint and he was counseled (should have been fired but the investigator covered for him - only so far up the chain you can chase corruption before your life/safety becomes a concern).

Years ago, a bunch of reform minded Boomers moved into a dying neighborhood in north Boston (a city known for its corruption over many decades). They were well educated, affluent, and politically active. They banded together, went to meetings, made their voices heard, and after a time, city politicos became more responsive to them. They showed how democracy can work, if one puts in the time.

Once you own some property and raise a family, you will probably find that you need to become involved in local government to get what you need from it, as have millions of others.
