Do we have a socialist system in the US?

Among the remaining communist governments, some (most notably the People's Republic of China) have added extensive modifications to their legal systems. In general, this is a result of their market-oriented economic changes, as well as their de facto abandoning of Marxism. However, some communist influence can still be seen - for example, in Chinese real estate law there is no unified concept of real property; the state owns all land but often not the structures that sit on that land. A rather complex ad-hoc system of use rights to land property has developed, and these use rights are the things being officially traded (rather than the property itself). In some cases (for example in the case of urban residential property), the system results in something that resembles real property transactions in other legal systems.
