There was a time in this country when working class Americans were actively engaged--and in truth, there still are some--but it seems that nowadays regular people like you and me are not politically active. I've been talking with some people for a while now, and I have come across this sort of cynicism about our system. To them, there is no hope of changing the system and making it work for ordinary people.
This sounds like a self-fulfilling prophecy, however; to not be active, stating that your interests aren't represented, only makes the situation worse. Ceding your vote is not the "solution" to the problem. It requires a resurgence in politically active movements of ordinary working people for such a change in this country to take place. It should not be viewed as impossible or highly unlikely! It was possible in the past, and it is certainly still possible today.
As for that video I linked, I know it's an exaggeration of the effects of such drugs. I just found it (somewhat) amusing and wanted to share it with you =P
This idea about the media's portrayal of drugs leads to another nice subject: the so-called "war on drugs." You know, that failed campaign by the government to fight against drug use by giving people who use marijuana life in prison and fighting (very ineffectively) the Mexican drug cartels.
I say legalize and tax it!
Actually, California came close to doing that--but the alcohol industry staged an effective propaganda campaign against legalization and thus the initiative failed. Maybe next time!
