This comic is backwards.

They aren't against this system, this system is their deliberate end goal.
Women who leave the workforce to raise kids are seen to them as "losing money".
Women who marry a man and don't work are seen to them simplistically as "losing money".

Women who have to work is exactly, explicitly what they're going for.
If they sell their bodies that's fine as long as it doesn't result in children or a permanent attachment that lets her leave working.
