> most people would want a wife
Are you sure about that? Maybe that was true in 1970ties or even yearly 2000, but today stats are pretty clear: most men do not want a wife!
Modern women have ethical troubles with making even simple sandwich. Tons of legal risks. 60% people today are overweight and on mental medication...
And fathers in families today are portraited as a homer simpson!
All the stuff wife brinks to the table, can be easily automated or outsourced at minimal cost!
