Step-by-step explanation:
Many young people complete their education and find it impossible to afford a new home despite having a well-paying job, yet their parents had a very different experience. This is an example of downward social mobility.
Downward social mobility is a movement from a higher social level to a lower social level. Young people move from a higher social class provided by their parents to a lower social class when independent due to a variety of reasons such as poor financial management, and inflation.
