I should have been clearer myself on some of this. I think the "do what you love" proponents are pretty much a poster child of survivor bias. Doesn't matter what you are attaining to, if you are able to get it, you are likely decently happy with yourself. If you failed at one thing and switch gears to another out of necessity, it is not that surprising that you would be less happy about it.
Consider the rock stars of academia in CS. Most are fairly happy and well off people with (or without, to their desire) families. Same for many studio artists. Not just the rock stars.
I think I get what you are saying, though. That to a large extent it is supply/demand. It is easier to attain a job if those two values are at least closer to equal than otherwise. Sports/musician/artist/professor/etc, in particular, are atrociously bad choices, just by the numbers.
I just fear that knowing which fields have a high demand is not enough to decide what field to go for. Many of them have higher demand than supply due to very valid reasons of physicality or mental difficulty. Though, I fully agree that this is a better decision attribute than "what do you love to do?"
