Joe blow is learning html again because he thinks its going to be easy money.

I don't think so: I think Joe Blow is learning basic coding skills because he realizes that virtually every job, or at least every intellectually engaged job, is going to need those skills soon, if they don't already. His company isn't going to fire him if he's the only one who knows how to update the blog and he's the one who wrote script automating that tedious task everyone else has to do.
