If what I see on Facebook is any indicator, then people are definitely waking up. When the Snowden story first broke, I heard a lot of people calling him "traitor" and now I am hearing more concern from those very same people, not about Snowden, but about the police state we live in. Then again, it's only Facebook. But the poll I posted above gives me hope that this could be a new trend.
I think America's biggest problem right now, what is causing this police state as well as our military aggression overseas, is greed, bottom line. The military-industrial complex is the strongest in our nation. It has bought and paid for all of our political representatives, so that they no longer represent the people but rather the lobbyists who bribe them (legally).
If we could eliminate public campaign funding, and ensure that every candidate gets equal and fair publicity, we might have a chance at turning things around I think. That was the original goal of the Occupy movement, before they got sidetracked trying to protest everything at the same time. But I have little hope that this will ever change, especially given prevalent attitudes in the United States.
I do know, however, that every time I gather with my friends, the overriding concern everyone has is the militarization of America, the loss of our freedoms, and the burgeoning police state. What we can actually DO about it is a completely different matter, unfortunately. I think nothing will change until some breaking point is reached, and people are still far too comfortable (and distracted) for that to happen here.
