Barriers to social mobility only affect individuals from low-income backgrounds and do not impact those from middle or upper-income backgrounds.

Barriers to social mobility can affect people from all income backgrounds, not just those from low-income families. While it's true that low-income individuals often face significant obstacles, such as limited access to quality education and job opportunities, middle and upper-income people can also experience barriers, though they may look different. For example, someone from a wealthy family might feel pressured to enter a certain career path or maintain a family business, which can limit their personal choices and aspirations. Additionally, social mobility is influenced by factors like race, gender, and geography, meaning that even those with resources can face challenges based on their identity or location. Therefore, it's essential to recognize that barriers to social mobility are complex and can impact everyone in various ways.
