We can come up with perfect solutions, perfect ideologies, perfect institutions. But in practice, nothing is perfect. We can talk about em, we can write about em, but we can't ever physically materialize anything perfect.
For example a perfect car is one that gives 100% efficiency for the fuel we supply it with. One that gives no sound, no heat, only translational motion. But in practice it is impossible to create such a car.
Capitalism similarly is something which many believe is a perfect institution, but like anything else is far from perfect in practice (and in theory too IMHO). So my question to those people who unashamedly blare the trumpets of capitalism, now that we have established that its not perfect, is that can you play the devil's advocate for yourselves and sit down and write down things that are not right about capitalism. I can list a whole lot myself but i'd like some champions of capitalism to sit down and list its problems.
Wonder what Obama would have to say.
