Not, she addressing an important point and counteracting typical conservative criticism before it happens. Fact is, a majority of doctors and lawyers aren't "rich" in the way people think when we criticize the wealthy. Doctors, lawyers, tenured college professors and other professionals with a good salary are still far, far below any threshold for what really makes the rich and powerful that influence politics and control the state of affairs.
Sure you have a few superstar lawyers (like Doucheowitz) and a few super-wealthy doctors (like the tiny percentage of successful plastic surgeons for the stars) but you also have far more doctors like those that take Medicare or work in the thousands of clinics around the country(and world) and plenty of lawyers who aren't the ambulance chasers with billboards all over town.
When I personally criticize the "richest Americans" I make the exact same disclaimer that she does because its important to differentiate salary earning professionals who might make a good living (say 200-350K per year) by the time they are in their 50s, but are not remotely in the leisure class, the wealthy people that truly control the vast majority of assets, people that pay far less taxes with their "unearned income" from investments. The salaried professionals are the ones that in reality pay the highest federal income tax rates as a share of income in the country. A bog-standard public defender or prosecutor or ER doctor with hundreds of thousands in education debt or even an eventual tenured university professor with great benefits will still pay far more in taxes (percentage wise) than Trump or Mitt Romney while not even earning remotely close to what the truly rich make.
So she is 100% spot on to make that distinction. Someone earning 100K is not fecking "rich" the same way the donor class of unearned income cnuts are rich and shouldn't be lobbed into the same bucket. Trying to lob a salaried professional (public defender, general practitioner that takes medicare, typical tenured professor) into the "rich" along with Trump, Romney, and the Kochs is the really disingenuous tactic that the right-wingers use to a great effect to subvert the message of progressives. Don't fall into the right-wing populist trap.
