By that i mean, by global standards, is our “Left Wing” really left wing? The Democrats and Republicans are both pro capitalist parties. They just differ on exactly how much social safety net we need. No serious republicans are advocating dismantling Social Security/Medicare/Unemployment insurance. And no serious Democrat, even the most “progressive” Democrat advocates seizing the means of production from capitalist.
There is a wide schism between the 2 parties on racism/sexism/and other social issues And that can be a very clear dividing line, but does it make a pro capitalist party “left”. In the context of domestic US politics we divide ourselves up into whether we are right of center or left or center. But it seems to me if you compare us globally and historically, most of us are right of center, we just differ on how much so.
