Yeah, but you know who gets even more screwed, salary-wise, than the professor? I'll tell you who: their lab techs and staff scientists ("research associates"), and that most definitely includes the "programmer who knows some science".

Furthermore, at least at my institution, being the "programmer who knows some science" means that your position is entirely funded with "soft money", which means that your level of job security can be pretty low.

I agree with your point, but I'd add the modifier that if you're a top-notch developer who forms an interest in a specific sub-discipline in science (my field is genomics, but there are many others where this would be equally applicable), there is certainly huge potential to carve out a niche and make a big name for yourself in your chosen field (as long as you take the science side as seriously as the coding side). Then you certainly could make big money, as Shaw implies and as you'd surmise from reading the linked article.

Everyone thinks they're underpaid, but the truth is, academic skills do not transfer well to industry. I refer you to the discussion in Ghostbusters:

"Personally, I liked the university. They gave us money and facilities, we didn't have to produce anything! You've never been out of college! You don't know what it's like out there! I've worked in the private sector. They expect results."

That's fair, but you know what those professors get? Tenure. ie not getting fired unless they're caught in bed with a live boy or a dead girl. And they typically get paid with hard money as stevenbedrick notes.
