Stealing was good for the majority of people in the financial services business who didn't get caught and go to jail.
The financial services industry, according to 2011 statistics, employed roughly 5.5 million people (and this is surely lower than the pre-2007 statistic). Do you honestly think that the majority of these people are thieves?
I could give one random person a million dollars and that would prove that people can escape poverty?
That's not how people escape poverty. People who rise up have to work to achieve it.
Your grasp on the use of statistics seems tenuous. It is not to prove possibility but likelihood. I could give one random person a million dollars and that would prove that people can escape poverty? Yes, they "can" but not at a rate or in a way that is meaningful for those stuck there or concerned about the problem.
