Financial independence gives students an idea or a concept to seek. It allows them to not have to work mindlessly at a job they do not enjoy until 65. Then they will have the rest of their life to enjoy their hobbies and passion. Life is far more valuable than working mindlessly for 40 years.
Once you start a job there is a little thing called taxes that has to be paid every year. It is the easiest way for the government to collect. If taxes were part of a financial literacy program in school then people would be able to take advantage and save money on doing taxes. Alas, it is not a money lesson taught in school.
With the use of tax advantaged accounts like 401ks, HSAs, and IRAs, you can reduce your adjusted gross income, and minimize the taxes you will have to pay. Even with a couple making $100K a year can reduce their taxes to $0. So take advantage of these accounts, and reap the benefits by paying less in taxes.
