I don't agree. I think the gender disparity in nursing is just as much a problem. I think it's a significantly less tractable problem though, because I don't think the monetary incentives are there for men to enter nursing.
As for your economic arguments, I think they're oversimplified. We really don't know what the job market is going to look like long-term. We do know that the computing job market has quadrupled in size over the past 20 years, and it is a good bet that the job market can quadruple again over the next 20 years, without any loss in median salary.
Back to monetary incentives. The median salary for software engineers could be reduced by 25% and it would still be a good career choice. So there's no real reason not to encourage more people to enter the field. Nursing has a substantially lower median salary.
