No country has ever been purely capitalist. There is always an element of socialism as governments provide services that have been collectively financed like national security. Right now, we are experimenting with seeing how much we can do without governance. For example, much more of the military is privatized now. We are working with the theory that government stands in the way of capitalism. Hopefully soon we will move on to a new phase where we realize capitalism unchecked will seek to overthrow or weaken governments. Then we can begin to build a framework that describes the checks and balances needed for governance. I will add that a government "for the people and by the people" must surely mean that inequality is not left unchecked.
