Who said that the vast majority of men should get into skilled trades? It's not an all or nothing sort of thing. Maybe some men are choosing a different path. 

Again,  comparing those with degreed and lumping in non-skilled labor, retail workers,  and underemployed along with skilled trades isn't an honest comparison. 

I've seen the struggling cubicle rats who are barely making enough to cover their x box subscription and student loan payments. If they work hard and pay those off, then they can work on buying a house and facing for retirement like their skilled labor brethren did 15 yeasts earlier. 

To say there is only one answer is lazy and dishonest.
