In a meritocratic society, how is social mobility primarily achieved in relation to social class?

In a meritocratic society, social mobility refers to the ability of individuals to move up or down the social class ladder based on their skills, talents, and efforts rather than their background or family wealth. This means that if someone works hard, gets a good education, and proves their abilities, they can achieve a higher social status, regardless of where they started. For example, a person from a low-income family can become a doctor if they study diligently and perform well in school, demonstrating that hard work can lead to success. The idea is that everyone has an equal opportunity to succeed based on their merits, which can help reduce the gaps between different social classes. However, it's important to note that not everyone has the same access to opportunities, which can make true meritocracy challenging to achieve.
