Teens and early 20 year olds are the most materialistic people ever. What a terrible time to be an adult. Full of show offs and peer pressure. I know many who have been humbled by reality as soon as they got older. Their materialistic personality has honestly ruined their lives (no financial planning, no discipline, debt, etc).
Word of advice to the kids: pay off your credit card balance in full by the end of the month, work on having a credit score of over 750 minimum, and save half your income while still living at home.
