Wouldn’t that just be “the left” with “the far left” reserved for MAP (minor attracted persons gag), ANTIFA, weather underground, etc type organizations that have their hopes invested in the left but see no support from the actual party.
Paul Graham seems to think labor is now winning since it is able to get capital to do startups much easier than in the past. But nobody on the left is criticizing this. The left criticizes the organization of these companies as they grow bigger. Anti-capitalism is the criticism that only a small group of people end up owning everything and making all the important decisions. The criticism is the anti-democratic nature of how most corporations function.
