The Prison System & Anarchy

So, earlier today, I attended an informational... show of sorts about the prison system in the united states. They kept saying "but capitalists won :( ". See, capitalism is constantly mistaken for something bad. Adam Smith did not intend for capitalism to be as we perceive it. It was supposed to be the small town competition between ma n' pa stores. This, what we have currently, this is not capitalism, this is corporatism. Sure, capitalism can develop into large scale corporatism, but there is a difference.
On a different note, they had their facts straight for the most part and did include some witty humor and did a good job of comparing the societal conditioning here to in Sweden, where the crimes are far less dangerous and don't require the type of "prison system" we have here. They also did an excellent job of explaining the mentality behind prison wardens and how people with that much power over "the bad guys" will abuse it more often than not. They also went on to explain how the legal system classifies innocent people and political prisoners as "criminals" and how harsh the treatment inside the prisons is.
But what I totally was just like "WHAT THE FUCK" at was their "solution". Well, if we don't like the prison system... what do we do about it? Well, their answer was "BURN THEM DOWN!" Are you fucking kidding me? Really? They were like "Well, it's the way society is, we'll fix society so we won't need prisons!" AGAIN, ARE YOU FUCKING KIDDING ME!?? Not to seem hostile here, but that's illogical and outrageous. What will we do with all the MS-13 members, rapists, murders, etc after we go and burn down the place where we contain them? Should we not do our best to end poverty and educate communities instead of going and burning these places down?
I hate anarchists who are so destructive and think that's the best way to create a societal revolution. But, they did give me a cookie... point is- Anarchy is associated with violence because of people with that kind of "I don't like it so I'll burn the motherfucker down!" mentality who claim to be anarchists. Other point being- we really do need to fix our prison system and unlike all the other anarchists, until we live in an anarchist society, I'm all for reform.
