It seems we are coming to the point where automation has significantly reduced the need for labor in producing basic commodities. It is particularly challenging when one has to advise college bound students as to what subjects offer a rewarding career. The essay speaks highly of the wages in the medical profession ... I think that part of the essay was misinformed. I don't know any medical professional who is not independently weathy and can get by on their salaries. They have massive loans to pay and if they have their own practice, they have to deal with TONS of crap .. insurance, marketing, and so on.
