There is no such thing as an "average left-wing socialist opinion". Socialists can be both right- and left-wing by your superficial spectrum. You are probably talking about Social Democrats, rarely labeled Socialist Democrats. Which is not the same as Socialists.
Again, it's obvious what I mean by socialists. It's not other groups using the word "socialist" in their name, like some communists (USSR) or national-socialists (Nationalsozialismus). I mean what universally is called "socialism" as a single word.
Perhaps you should check your own biases. The political spectrum comes from Europe. And I'm not American.

My point stands, this post adds nothing of value. Even as opinion is a very average socialist position we've heard many, many times.
