I notice that a lot of people who criticize the poor and say they should work harder and be more responsible seem to assume that middle- and upper-class people are where they are because they work hard and are responsible. The fact is, many middle- and upper-middle class people are there for the same reason the poor are: because that's where they were born. And middle- and upper-middle-class lives come with privileges we often don't notice.
Take me, for example. Both my parents majored in journalism and became advertising writers. My grandfather was the editor of a medium-sized newspaper. So I became ... a writer! Based on a journalism degree ... that my dad paid for!
I grew up in a nice safe pleasant neighborhood, ate reasonably healthy food, was raised by college-educated parents who weren't unduly stressed, had free time to care for me, could afford to take me on trips and buy me books and art supplies. I attended some of the country's best public schools, was expected to go on to college and get a good job because ... well, because in my family and my community that's just what you did.
There was also room for error. In high school, a nearby teen clinic dispensed birth control to girls my age. We got there by driving there in our parents' cars that they let us use. Some girls got pregnant anyway, but I don't remember anyone in high school carrying a baby to term. They got abortions, I guess, because having babies would have interfered with their plans to graduate and, in most cases, go on to college and get good jobs. In high school and college, I partied and took drugs and skipped school and bad stuff like that. I could afford to break some rules, because I had the safety net of money and security and high expectations.
So suppose my background had been different. Suppose instead of being surrounded by educated middle-class people, I grew up surrounded by undereducated people who didn't work, had babies as teenagers, sold drugs, etc. Well, then I'd probably do all those things.
Of course, there are people who transcend such hardships and go on to great achievements. But many, perhaps most, people are simply not that ambitious or smart or strong-willed or confident or rebellious or whatever it would take to rise above the environment in which they're immersed. I don't think I necessarily would have.
