not sure if that is the main motivation. men want to see their wives as equal partners and hence the preference for educated partners. it also makes sense if they are capable of standing on their feet in the event of unexpected events such as divorce, death of husband, etc. yes, some men might want to go for the "homely" types if all they are all looking for is a cook and a slave!
