Correct meaning what? I'm interpreting "the traditional left" as a value system instead of a set of statements about the world.
Correct meaning that we would prefer the outcomes of their policy suggestions to the outcomes of other policies, or I guess generically that their values are an effective mechanism for generating good policies.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
