Sense, Nonsense, and Not-Sense

Well, the article there talks about the barrier to college, and most higher-paying jobs require college degrees as the entry requirement, so that's part of it.

Then, there's articles like this Washington Post article about the hidden costs of poverty, in time, in not being able to go to the Big Box store to fill up a car and a fridge, and so on that also affect job prospects - if your commute is limited to where the bus goes, that limits job prospects, too.

So people growing up poor may have their ability to earn limited simply because their parents can't provide enough of a boost for someone to get the things that will help create a middle class life.

And that's without the issues of gang life, crime, and unsafe living conditions that take a lot of people out of their earning potential, too.
