Do you have some statistical evidence to support the claim that people from low income and bad families are overrepresented in the higher echelons of sports of engineering? I strongly suspect quite the opposite is true. It is not sufficient to view a few examples - after all, a huge portion of the population comes from 'really poor and troubled backgrounds'.

No I don't. It is just an observation. Now in for e.g. India there are a lot of people going into engineering or medicine as a way out of poverty. So you are right but now it is the profession through which to get out of poverty and there will be a lot of people from poor and troubled families in it.
