Non-Marxist leftist discourse on the so-called PMC (= false & useless abstraction, for occupations are not the same as & in fact cut across classes) is highly useful for neoliberals. Observe how neoliberals (especially neoliberals who used to be leftists) put their mastery of "developed theories of stratification" to good use. Fake populist demagoguery against the "PMC" -- doctors, lawyers, teachers, social workers, etc. -- is essential to the art of cutting back social programs for & making legislations more punitive toward the entire working class.
Think about the politics of student loans: propaganda against "deadbeat doctors" creating a wedge to decrease support for lax enforcement of loan collections, thus making it easier to enact wage garnishments & the like that assault workers. The tort reform propaganda attacks "greedy lawyers" to make corporations safe from lawsuits by workers. The bankruptcy reform began with exposes of "inexcusable abuses by the privileged" (= those who go bankrupt but remain rich, while weaseling out of their obligations) & then went after its real target: working-class debtors. The welfare reform used rage against "deadbeat dads" to make the lives of poor women miserable. Derogate "pointy-headed professors who refuse to teach undergrads" to diminish support for state funding for tertiary education. Scorn "incompetent public school teachers who couldn't care less about poor minority students" to avert attention away from atrocious inequality in public school financing. Low payments for public defenders -- justified on the assumption that saintly lawyers should & would work for practically nothing -- to take away the rights of defendants. And so on, and so forth.
Neoliberals (who are often neo-conservatives & know a thing or two about Barbara Ehrenreich & the like) are very good at making use of criticisms of the "PMC", male privilege, white privilege, etc. -- erstwhile specialties of leftists -- to attain their ends.
