It may be true for you. I doubt it's true for me. And most importantly, I doubt it's true for the average male. Hence not much of a surprise that people aren't going around signaling frugality and trying to support a family with one earner on a relatively low income.
The average ;male isn't frugal, either.
It's like any other unusual trait which works best with a cooperating partner.
