>The "Lump of Labor" fallacy is just that, a fallacy. Economic gains are not zero-sum.

One of the consequences of women entering the labor force is banks will lend on the basis of two salaries instead of one. In a world of constrained housing supply (which seems to be most of the west) this means prices will be bid up to match the joint income.

This looks awfully like a zero-sum outcome to me.
