Interesting. Some friends and I were talking about this the other night. I have a few friends who actually "made it" but still haven't learned those essential skills. I wonder what may happen if one day they happen to face tight budget. They probably wouldn't last long.
Some background: My mom made about $8000 a year, and my three siblings and I we were lucky to have temporarily free housing from a richer sibling. So, with food stamps, welfare, my absent dad's union health insurance we got by.
Eventually, I found my way into a gifted program at a small, urban city school. That, at least, put me on an academic track. My class size was about 400, and the gifted group was about 15. By the end of the 12th year, I would guess that, of my gifted class, probably 40% had dropped out. The class merged with the honors students in 11th grade because of attrition. However, I made friends with some honors students who were of working class and poor backgrounds.
Again, by sheer luck, I happened to get accepted at a state college. After meandering around for a couple of years, I happened to made the right decision by banking on computer science, even though I had never used a computer until I was 15 and didn't own one until my junior year of college. Those years of constantly fighting with the student aid program were some of the most stressful years of my life. Now, I make over 100K as a high-end developer. I have done well for myself.
However, most of the other gifted and honors students haven't fared so well. I do have a few friends that have also done well using Computer Science as a gateway out of poverty. However, those friends sadly still haven't figured out how to do basic bookkeeping or balance their checkbooks. But, in all honesty, I did not figure that out until I was 28 or so.
Anyway, without savings, with poor life skills, and a lot of debt, even those smart kids are probably likely at risk. If ever the software development market turns down, if they're out of a job for an extended period of time, I wonder what will happen to them, as well.
