Don't get confused, the argument over capitalism vs socialism is most concerned with the area of economic practices. self correcting markets based on individual incentives, curbed by competition is what has created the largest, most complex and diverse economy the world has ever seen. Areas where no incentives exist to create opportunities for individuals obviously cannot thrive under those conditions and would need state intervention to exist, such as a legal system, the military, law enforcement and social welfare.
The wealth and opportunities available to countries in the european union is the perfect case against socialist economic planning, and exactly why england peaced out. what exists is a system of haves and have nots, inspired by the flick of a wrist by a group of crony politicians in brussels. so while some countries may enjoy the fruits of excessive wealth and opportunity redistribution, other fall into abject poverty. and that's why many predict the european union is soon to fail. thanks for pointing that out.
