Nobody's taking to the streets over the PRISM thing because they would be called "violent thugs" for doing so.
There is a real undercurrent in our country associating taking action (any kind of action) against the government with violence, and violence with everything bad, which shames and discourages people from actively taking part in political discourse.
People like you who call others "violent thugs" help the government spread that notion and keep people under control. You'd probably call the Founding Fathers "violent thugs" and call them traitors too.
Blaming the problem on violence is the act of a myopic ideologue. Violence is a symptom of the greater problem -- fascism -- not the cause of it. Rampant use of violence on a citizenry by a state is always a sign of fascism. Really, the U.S. government's non-violent ways of controlling the populace -- massive propaganda, spying and such -- is much more destructive, damaging, and far reaching than their violent actions. Their use of violence damages their credibility if anything.
As for the notion that being violent is profitable and that's what keeps the wheels turning -- considering how badly it tends to make local police forces and the U.S. government look when they're caught, I question this premise. How to make it unprofitable, though? Well, you can't. There are economic forces driving the violence which are powered by demand, and that demand is powered by many things including human nature itself. Not even the intervention of a state will get rid of the demand and where there's demand, economic forces will always find a way. Exhibit A: the drug war. Unless you switched to some other economic system there will always be a market for violence, and even then it'd never truly go away.
Instead of trying to get rid of violence, you need to focus your effort on getting rid of the circumstances that cause people to feel they have to use violence -- bullying, abuse, poverty, the like. We all know the fabled story of the schoolyard bully: he basically dominates because he can emotionally abuse and torture someone to the point where they use violence to make it stop, then use the system around them to get their victim into trouble, gaining complete and utter control over them. You would call the victim the "violent thug". The real (and just) solution would be to punish the bully in the first place. See what I mean?
Poverty's also a huge driving force in the use of violence. Lack of resources cause people to compete with one another for what crumbs exist, oftentimes violently, it strains relationships, destroys kids' ability to grow properly, etc. etc. If everyone had enough stuff to live comfortably and had no reason to worry they'd lose said comfort at some point in their life, they'd stop looking at their neighbor as competition and instead as a potential friend.
Money is the key to world peace, my friend, not hippie shit.
