In contrast to a capitalist society, how does a persons income function in a socialist society?

A persons income functions similarly in both capitalists and socialist societies today. "Socialism" as an idea or theoretical economic model has not been fully implemented in most societies that use some socialist concepts. In European countries like France, Sweden, or Denmark they use both principles of capitalism and socialism. In that they are integrated into the global economy and take part in trade and also regular business they are capitalists, however, they have large social protections in the form of government services etc. which are paid for with high taxes. The major difference in incomes in these two systems are that in capitalist societies tend to have lower taxes than socialist societies, but give less state services or welfare than socialist societies.
