Socialism is a very attractive political theory until there's no more OP money to support it.
One can also say that corporatism (which is where we are now, capitalism isn't the correct term anymore) is a very attractive economic theory until all the money has been accumulated by only a few and nobody else has any money left to buy anything from them. (US being a good example of that)
So maybe we need to find a good balance between the two systems?
