You miss the point.
why the low view exists is irrelevant.
Frankly, while I acknowledge their necessity, I have a poor (default) view of both bankers and lawyers. I don't see them as bad people, but people in their professions do many bad things.
If my son brings a banker home as a prospective mate, well, let's say they're not earning status points from their profession.
You (may have) and I (do) have respect for people in tough jobs like see workers. Doesn't mean my mom wouldn't prefer I date a nice doctor. My point being that social respect does not come with your personal respect.
