I don't know how many typical hourly workers are going to be able to be reasonably trained for it, but there are some. The vast demand for it and tech workers should pull them in. But it doesn't, cost is one reason, but a bigger reason is it's hard or they think they can't do it or are actively dis-interested.

One way to see this is that a million people every year who are already in college choose not to study cs or it type things. They could do it as part of regular college but they don't. Then they get out and can't get a job.
