Which of the following is NOT considered a barrier to social mobility in the context of social stratification?

A barrier to social mobility is something that makes it hard for people to change their social or economic status. Common barriers include lack of education, poverty, and discrimination, which can keep people stuck in the same social class. However, a supportive family environment can actually help promote social mobility by providing encouragement and resources. For example, if a child has parents who value education and help them with their studies, that child is more likely to succeed in school and eventually move up in social class. Therefore, a supportive family is NOT considered a barrier to social mobility; instead, it can be a helpful factor in overcoming other barriers.
