The simple fact of the matter is there are hidden biases against men completing college, that favor women completing college.
The same holds true to a large degree in employment with few exceptions.
Making a supposition that the pool of female to male candidates for college is interconnected is a fallacy. It is independent, and based on factors with no current visibility, and there are no guaranteed prospects even if men can somehow complete the struggle session to a degree.
What's worse. Women don't date down. So all those women who got degrees will have a harder time finding mates, will be the bread winner which leaves the men in a role that is unattractive to them, and they will be highly dissatisfied as a result of simple math and gender selection differences.
You don't survive by ignoring reality, and birthrate collapse is going to happen given the myriad of issues that people can't seem to get a mental grasp enough to recognize the underlying problems. When there is a problem, and people can't communicate sufficiently to organize to recognize said problem, nothing gets done. You can't react, and the problem grows until it can't grow any more (at existential crisis). Cascading failures are diabolical because people cannot believe that certain little things cause great big things in time. Evolutionary selection eventually destroys societies based in total control, as those members cannot adapt and fail Darwinian fitness.
