hard work is racist, says professor
I don't see where you got that from what's in the OP.
Based on what little there is in the OP, all she appears to be saying is "cultural norms tend to be self reinforcing and self perpetuating. Reinforcing the ideas and beliefs of the predominate group, which creates a system to protect the culture and norms, and is then used to perpetuate and reinforce them."
IMO little different than an article saying "the existence of roads and ubiquitous gas stations perpetuate vehicle and driving ideology. The professor designed a seminar on driving privilege then interviewed 12 attendees on their belief in looking before you cross and not jaywalking and preferring driving to walking. Driveness ideologies."
At best you can say the professor is a progressive, possibly wanting constant change.
At worst she's attempting to justify her continued employment by trying to prove her area of expertise (which are her beliefs) are valuable and worth teaching.
Otherwise it's just an article meant to manipulate outrage.
Click bait at best.
