I get where you are going with this, but I think that over-generalizations about male/female workers is less absolute, especially today.

I've lifted heave loads at work, done physical jobs, repaired my own truck with new parts, changed oil, done home repairs, built fences, and yes, I am a feminist as well.

Another point is that men do not have to only do low-paying, physical work. They can go to trade school, or college, or otherwise develop skills that pay more and wear less on their bodies if they are that dissatisfied.
