I don't really think it's "culture." I think that culture and the environment you grow up in can make you think something is a good idea or even "cool." People might not feel like there is a better option. But I think ultimately the issue is that there really isn't much of a better option. De-unionization and wage stagnation has made it basically impossible to live with any dignity on a multiple tiers of jobs. Maybe the culture that certain classes of people don't deserve a living wage is contributing to this?
