“It should come as no great surprise that a Democratic Party which has abandoned working class people would find that the working class has abandoned them,” Sanders said.
“First, it was the white working class, and now it is Latino and Black workers as well. While the Democratic leadership defends the status quo, the American people are angry and want change. And they’re right.”
“Will the big money interests and well-paid consultants who control the Democratic Party learn any real lessons from this disastrous campaign?” Sanders asked.
“Will they understand the pain and political alienation that tens of millions of Americans are experiencing? Do they have any ideas as to how we can take on the increasingly powerful Oligarchy which has so much economic and political power? Probably not.”
Depends on what definition you use, classically a social Democrat is someone who believes in using democratic means to gradually and peacefully transition from capitalism to socialism. The definition you are using is actually closer to a social liberal but even that isn’t quite right, welfare does not imply a mixed market economy on its own, welfare can exist in a pure laissez fair market economy. Social liberalism is in favor a mixed market economy which is a further step left from simply a regulated market economy with welfare. In a mixed market economy key industries are publicized and owned and operated by the government for the public benefit while allowing for the possibility of private competition as well as an open market economy in other industries and areas.
