The problem with the left is a total disregard of biology. Chromosomes don't determine sex, feelings do. Reproduction, according to the state, is inconsequential and 'love' and 'feelings' are paramount.
So it is difficult to talk about the 'mating game' and men going there own way without going back to a time when marriage had a purpose. With that in mind we can never forget that the eukaryote has always been at war with the eusocial.
Nothing destroys a man's wealth faster than a failed marriage. And today, women have all the power and with that have no incentive to stay in a marriage if it gets in trouble. Since women have no incentive to stay in a marriage, men have no incentive in joining one.
So, if the benefit of the whole does not disrupt the benefit of the individual, more men might be enticed into getting married and starting a family. But those days are gone.
Seems that way to me. Just look at all those shows lauding conspicuous consumption around marriage, for example, "Say Yes to the Dress". More about being a Disney Princess for a day.
The breakup of the family is precisely why government has gotten as big as it has. There is a void to be filled, and it will get filled.
