"Policies that remove gender based barriers to employment are good for the economy, due to the basic fact of life that housewife is a ludicrously low-productivity job sector".

What do you mean "remove gender barriers"? Do you mean policies requiring companies to hire be "non-sexist" in their hiring practices etc.? Because if those practices increased productivity companies would use them anyway.

Heck, near as I can tell, a good chunk of the wealth gain's of the past 50 years has mostly been the working out of the productivity implications of household appliances - 2 income households are possible because the electric stove, the refrigerator and the vaccum means keeping house isn't a full time job.

Also have both spouses work tends to result in the couple having a lot fewer children. In fact in another thread people were complaining that they couldn't afford to have kids because they couldn't subsist on one income.
