Actually, you're factually wrong on both counts. You largely are merely spewing the poisonous propaganda from mindless talking heads and partisans who can't see that when their side does the exact same thing is all of the sudden market driven. Also, next no economy in the world today is purely capitalistic nor socialistic. They use different mixed forms which are actually something else altogether. Only the blind see one or the other.
Furthermore, there are real, tangible, and rational reasons why this is. Pure forms also have problems. And often lack the flexibility to handle serious problems that transpire. A pragmatic approach recognizes this and seeks to make proper adjustments where possible. But even with such a problem solving approach, the government can only go so far, unless you're China. We cannot outlaw out sourcing fir example. Understanding where government doesn't have control of any kind is important. It is also important to understand if government had complete control, like in China, there would Ben no regulations. None. So, to get what you want concerning regulations, you have to have government run business, or at least a government willing to ignore and not respond to the citizens of this country. So, again, many are not thinking it through. They merely choose a IDE and spew vomit without thought.
