> You write as if there is a division of work between the couple. That would be true if men and women could decide who would stay at home and who would work at a company. In fact, men are required by their society to go to work, so this is in fact a relation of oppression.
So I reject your assertion that this is a relation of oppression, unless you are conceding that both members of the relation are equally oppressed (in which case, I would argue that nobody is).
You appear to be conflating value with compensation. Unfortunately society often seems to value the work done by the at-homeartner less. That is a different issue than compensation. The issue of compensation is personal to the relationship. To say one person is uncompensated completely ignores the fact that it is a partnership with a pool of resources and a pool of responsibilities. Sometimes there's more or less choice in involved in how those responsibilities are distributed, but dividing things into one person does this and gets this etc., acts as if there were two separate systems. There aren't. It's a relationship, a single system.
That feeling of performing uncompensated work is what OP is claiming MLMs are taking advantage of.
If your entire social and economic network is built around the totalizing influence of (the conservative end of a) religious institution, and if that institution says that women should stay at home, then there's a de facto barrier to full participation in the labor force. So, the stay-at-home parent will be the woman.
Fortunately, there's a "way out" that there wasn't in previous generations: "just" leave the church. Unfortunately, saying that's far easier said than done is the under-statement of a century.
