Decrease in Activism?

What happened to the days when college students openly demonstrated in public? I think activism has decreased in teh past decade or so with our generation. Back in the 60's and 70's, more students followed our country's politics and issues more closely than we do now. I think that we have become distracted with material fantasies and pointless technologies. We are losing focus on things that are going on that will shape the world we live in. We aren't aggressive enough with the protection of our rights and when we want something from our government, we shouldn't just leave it to Congress and a few interest groups, but rather take the matter into our own hands and demand it till we get it. What better way to let our elected officials know what we really want?
