My stepson and my husband's best friend both LOVE shopping, and neither of them are mystery shoppers. Even though traditional gender roles are changing, there is still an expectation of men in many instances of being breadwinners and head of household, and they don't have the luxury of taking their time and a paycut while building their MS businesses. I think more men would be MSers if their wives were the breadwinners and they were the ones staying home raising the kids.
