Implying that the ordinary person has the opportunity to make more than another person's entire family is -- by it's nature -- a joke. You can't be anywhere near average and make more earn more than 3+ average people. Using a normal distribution, that puts you a MINIMUM of 3 standard deviations above average -- literally the 0.1%. Using the actual income distribution (since it's distinctively NOT normal) -- it puts you in the top 2%. But if you actually work for a living (as opposed to collect returns on investments), it's likely in the top 0.1%.
A state senator is likely to be above average -- as are family members. In general, we don't strive to elect average. We strive to elect excellence.
Maybe it was meant to be a pep-talk. But just because one person dropped out of school and did well, doesn't mean that everyone can do the same. Maybe the OP is a genius. If not, he got lucky. And not everyone can be a genius or lucky.
