"If capable people want to work, they can." This gets to what I was discussing.
1. What sorts of jobs are available to the group I cited? Make this a matter of rational choice. What will many of them choose?
2. Define "capable."
It's essentially like what happens in our schools. We all accept that cognitively disabled kids with IQs in the 70s aren't going to be able to the work required of other students, but we pretend that the kids with IQs of 85 or 90 can do the same things the kids with 120 IQs can do. They can't. So some accuse the low-end students of being "lazy" and then others pretend that there's no such thing as inherent intelligence or that it has no bearing on how students perform. We're all malleable and if we just teach these kids better and spend more resources, they'll be able to do whatever they want to do in life. It's a fantasy world, just as it's a fantasy world to pretend that as adults, it's all just a matter of hard work.
It's a very frustrating thing as a kid to be demanded to do things you're incapable of doing. It's a very frustrating thing as an adult to be demanded to do things you're incapable of doing, and be labeled "lazy" when you fail at them. And then add into to it that you've been socialized with all sorts of self-destructive, counterproductive values and you have a lot of unemployable people who drift from job-to-job.
You probably have many underemployed people who have now moved up to appropriate employment to their abilities. I don't know what you do with the group I mentioned above as our economy demands more and more technical knowledge, abstract thinking skills and complex skills to perform ordinary jobs. We need to prepare for that and talk honestly about it.
