Most likely the Clinton wing is the wing that is more likely to emphasize social issues while the Sanders wing is more likely to emphasize economic issues.
Separating "social issues" from "economic issues" is a fool's errand, but yes, the Clintons of the Democratic Party do tend to ramp up the cultural warfare in their rhetoric in comparison to the party's populists. Of course, once the former actually get into office, they end up doing zilch to end mass deportations or police brutality, and, needless to say, put no effort into passing social democratic policies that improve the material conditions of the working class. (in particular it's non-white, non-male segments)
In order to separate social concerns from economic anxiety, one needs to see the treatment of rich black people such as Lebron James are treated by white society. Lebron house was grafted by racial slurs and he's the richest player in the NBA, don't see how having tons of cash will erased racism. The economic populism doesn't take into consideration that much of the country is deeply ingrained in racism. If a single payer health care system is established it wouldn't be easy to see how the Deep South would forbid immigrants from having health care, or blacks even. Blacks or other minorities, not matter the class, will face the same struggles in their daily lives, therefore it's condescending to hear rich white people say social democracy would be better for them when they have the weakest power in Scandinavia nations.
Rich people cannot be "oppressed" regardless of race.
People of marginalized background can be discriminated regardless of income. Rich women and POC face more discrimination in their daily lives then poor white people.
Boy I wish this was true!
