People have grown up and been raised in a culture that for a brief period in time was an exception. It's just between the 1940s and 2000 that we ever had a society where almost all when where able to mary and have a family.

This period is over, and if you want to marry and have kids you better put down the same amount work people used to.

Men just got to accept their lot in life or work to change it, like all other people in history have had to do.
