Are we solely a capitalistic country in terms of economy or are we somewhere between socialism and capitalism?

[Gavin R]

The public utilities are a socialist element in that they are owned by the municipalities they serve. The Social Security system had socialist roots, but it also happens to be humane, and now every major country has such a system.
Capitalism has its good points and its bad points - no economic theory is perfect. A problem with unregulated capitalism is that mergers become larger and larger until there is a monopoly, and that's not a free market at all. Sweden has a mixed socialist and capitalist economy. Swedes enjoy a much higher standard of living than Americans do. France and the UK also have mixed economies, and yet the citizens there have all the liberties we do and many more benefits for workers.
