People from professional white-collar backgrounds tend to want to manage things. They want to oversee and plan and organize. And their partners who come from blue-collar backgrounds, working-class backgrounds, often tend want to go with the flow more. They let things come and feel free from self-imposed constraints. An example may be with emotions. People from professional white-collar backgrounds want to manage their emotions more often, meaning they want to think about them before they express them, consider how they feel, plan how they're going to express them if they do at all, and say it in this very intellectualized manner. And their partners who come from blue-collar backgrounds who believe in going with the flow a lot more expressed their emotions as they felt them and did it in a more honest way. - www.vox.com
