What Sanders means by democratic socialism

See this article and video. Speaking of Scandinavian examples he said:

"You have all kinds of capitalist entrepreneurship going on, a lot of wealth being created. But what else do you have? … An effort to make sure that all people benefit from the wealth that’s being created. So you have a much more equitable distribution of wealth and income."

This is the same form of democratic and socialist capitalism Robert Reich talks about. And it is the necessary socio-economic system that sets the stage for the emerging neo-Commons.
