>> By marrying, a man becomes a better employment risk. Married men usually are regarded as more steady, more trustworthy employees than single men. This is logical. Marriage exerts a stabilizing influence on most men.

Oh wow has that changed. Kids and families = time away from the office. Marriage is also the leading cause of divorce, which tends to reduce productivity across a few years, especially if child custody is an issue. And, contrary to past working conditions where promotions were steady, a married person with a young family is now probably more likely to jump ship for a better job at higher pay rather that wait out a decade for in-house promotions.
