The reason most poor people are poor is not due to lack of earning potential, but 1. poor money management skills and 2. they just don't choose to work all that much. I remember that there was a study a couple of years ago that said the families with the top 10% in incomes (this is from memory so might be off a bit) worked 100+ hours a week. Families with lowest 20% income worked 20 or fewer hours a week.
Are you suggesting that it's some sort of personal responsibility to have initiative enough to work for money? Dick Gephardt told me it was all about a lottery.
