The major contributor to the decline in marriage is a culture and a government that does not respect the institution that has existed since the Christianization of Europe. With divorce laws and child custody arrangements as they currently exist, there is no financial incentive and many disincentives for men to get married. The feminist ideology is especially poisonous, as is the radical egalitarianism that pervades American and other Western societies.
Conservatives have gone down the same slippery slope as the rest of society. In the 2010s, conservatives who support equality of opportunity are to the left of 1930s socialists who advocated "living wages" for heads of households, who were overwhelmingly male. Twenty years ago, the thought of women in combat roles was anathema. Today, it is barely questioned, even in front line positions and on submarines.
No recovery will occur until such time as conservatives become true to their name, look at the longer time rather than the next election cycle, and stop advocating the positions of liberals 20 to 50 years ago.
I hope to live to see the day where tomorrow’s rebels are the polar opposites of the 60s counterculture crowd.
It's no picnic for women, either, although individual cases vary. The way it now works is that the person who invested the least in the marriage and the children will prevail against the one who sacrificed for the marriage and childcare. Could be the man, could be the woman.
The divorce industry and so-called "no-fault" jurisprudence create winners and losers; but there can be no winners in marriage. Marriage requires teamwork and sacrifice for the good of all. An increasingly foreign concept.
And let's not forget: the lawyers always win first before anyone else.
