Oftentimes, I hear people talk about how great polygamy was for women and all the benefits it had for them. Plural wives had fewer children and live-in child care in the form of sister-wives, and so were able to pursue more interests outside the home. They were more active in politics and religion. Some of the things you read from Brigham Young were actually pretty liberal. He encouraged women to be doctors, wear pants, and so on. The whole suffrage thing was a big hit in Utah, too.
Those things sound awesome, so let's replicate those benefits. Women should have fewer children and take advantage of child-care options available in their community. They should be involved in politics and other community endeavours outside the home. Come on, guys, we don't need polygamy!
As a side note, I think the whole health care profession should be run by women. They're just better at it. I say the entire field belongs to women. So bring on the communal child-care. That is, after all, what was so great about polygamy, right?
