(Commentary) According to University of Virginia sociologists Bradford Wilcox and Steven Nock, co-authors of the study 'What's Love Got to Do With It? Equality, Equity, Commitment and Women's Marital Quality' women are usually happier when their husbands earn most of the household income. "Our study suggests that women who take a man's wealth into consideration when dating are likely to be happier down the line," explains Wilcox.
