"he would be expected to lead his family, to provide, to sacrifice, to labor, console and bring the energies of an entire family to bear fruit"
You forgot to mention the other half of the equation. In return for this selflessness, man's home was supposed to be his castle. The man was supposed ot be respected and deferred to. It's a social contract.
Women broke the social contract first. Any group that breaks a "social contract" has no right to be mad if the other gives up on their half ot the "contract".
You know who is also a fool? Anyone who continues to honor a contract even though the other person is completely ignoring their own obligations under the contract. Despite what you see on TV, most men aren't fools.
