This is backwards - in order to see how people treat people based on their profession, you can't make friends with them... because then they aren't judging you on your profession any more, are they?

If the exact same person is treated in two different ways, and absolutely nothing changes except their profession, then the profession is the only possible cause of the difference.

You try it! Go into an environment presenting with one profession, then another, and see the difference! Book into a hotel describing yourself as 'doctor' and you'll get treated differently than when you book in as 'mister'. You can try it yourself and it's plainly obvious that society sees a difference.

> it's not truly high status

I think you're possibly lost track of where this started - I said A was lower than the B. You're trying to argue with me that B isn't the highest, but I never said that - you're arguing against something nobody said in the first place.
