Governments role

In communism the government doesn't have much that they don't control. The decide what you get in your pay check and decide what hours you work. They take your paycheck and take out everything they want and give you what they think you need, and they don't show you how much they take out or how much you could have made. The government officials are chosen by who the leader chooses and usually they are close friends or relatives. Health care isn't something that can be disputed against you have what they give you, and you only get that specific healthcare.

In a mixed economy the government only controls what they own such as land and the things on that land. Depending on what they own is what they can only control. They tax but they take out the taxes after you get your paycheck to see what you earned before and show that they only take what they need. And you get the rest. The government officials are chosen through voting and seeing who the people want more. The health care system is what you want and what you can pay for.
