I cannot speak for others, BUT..... I lost my corporate job right after 9-11. My wife had been working part-time at a school in order to "keep an eye on our son" (disabled). When I got laid off she saw an opportunity to go full-time and accepted. So, in essence we switched roles.
This allowed me to stay at home and focus on an idea I had to start an internet business AND take care of my son when he was not in school. So, I became a full-time "house-husband". Fast forward: the business took off and I have been a "house husband" for over 20 years now.
My spouse works hard in her job, so I make sure the dishes are done, the floors are vacuumed regularly and the laundry is done so that when she gets home she can just relax. Yes, she still looks for "things not done".... and I do think there might be a slight inkling of "jealousy" there.... but it works for us.
Of course, I can't see every guy being as flexible as I am.... so, "your mileage may vary".....
