And adaptation is a real challenge, because it may mean learning completely new technical skills as well as completely new social and political skills as well as being unusually creative and inventive - and most men have to attempt this after a very poor education and little or no mentoring or modelling of the possibilities.
In the past, men could get by fairly passively because the job-market was full of ready-made slots for them. They could turn up and fill a slot and money would start flowing.
Now the slots have to be invented before they can be filled. That immediately disenfranchises the 90% or so of the population who aren't particularly creative or entrepreneurial.
And even if a slot is invented, the odds of lasting success aren't great. Most projects fail, and failure isn't tolerated well.
So we've gone from an open job market with limited selection pressure and relatively easy rewards to a very closed and challenging job market which only works for maybe 5% of the male population - specifically unusually intelligent, creative/inventive, socially connected and/or wealthy, or just plain sociopathic men.
It's a huge, huge change, and I don't think we've even started to see the effects.
