Oh, Let Me Count the Careers I'm Not Able

I don't know who to blame this on. I am able a good number of careers that I don't qualify and am not physically capable of. Tell me what good it is for civilization, and the individuals themselves, to train youngsters in careers that will flatline? I'm willing to argue that a good chunk of American population has been fed to 1 revolving door or another, without the slightest inkling of whether it benefits the individual, or the individuals community. I may sound bitter, I'm not. In fact I have less compassion for these folks than most. And that's why I feel they are being killed, royally, without good reason, and should be helped more than they are.
