I disagree. If one looks up Socialism, there are pages and pages of varying types. Look up Adam Smith who promoted Capitalism where the producers and buyers come together, with buyers having all the information to make informed purchase decisions, and tell me how that happens today with multinational companies obscuring product information, engaging in monopolies and price fixing.
Sanders promotion of Democratic Socialism is not about owning the Mom and Pop stores. It is about protecting the consumer from the onslaught of corporate power, where corporations are people, where they can buy Congress in hidden processes. If that is Capitalism, Adam Smith did not envision it as such. 
We all pay no matter what. Right now we are all paying for products and services the profits of which are funneled into offshore accounts. And we are left with pollution and Wal Mart workers on food stamps who live in public housing we all pay for.
Time to move on from a politics of fear.
