What is the "mix" in the US economy relative to most other countries' economies?
Your question is asking about mixed economies. The US is indeed a mixed economy, meaning a blend between a capitalist society and government-controlled economics. The US economy is capitalist in ideal but is still regulated by laws in regard to trade sales, and the government owns roads, utilities, and many other sectors.
There are a variety of mixed economies throughout the world. It is most common to find mixed economies. China for example was a state owned and thus not really mixed economy, but since the 1990s has been becoming progressively more mixed and open to capitalist enterprise. North Korea would be an example of a non-mixed economy. North Korea is an extreme example of socialism. The US draws on socialist notions in such things as welfare and state regulations on business, yet primarily the US is capitalist.
