Depends on the job, depends on the marriage. My wife had a lesser paying job which demanded more time than mine, so I did the greater part of the routine kid stuff, housework, grocery shopping & cooking. When she retired (before I did) that changed around. Now we divide things fairly but not equally. Basically, a good marriage is the only workable communist society – “from each according to their ability, to each according to their need.”
