More women in the workplace, means more labor supply = downward pressure on wages.
Not to mention offshoring.
I would attribute downward pressure on wages to the ready access we have to goods made in China where the currency is manipulated for the express purpose of making their goods cheap in the US. A classic case of “the cheapest goods aren’t always the least expensive goods.”
Simple, when one “levels the playing field” they don’t move people up, they move people down to the lowest denominator.
Wait till all those illegals start competing for those wages!
