Everyone wants a job that pays well. Some people stop school early because they want to start earning cash right away. Others spend years and years studying in school in order to get a better job. Which is best? Actually, studies show that in most jobs, the higher your education, the higher your earning power.
For example, in the United States, high school graduates can make about $30,400 a year. The people who do not finish high school average only $23,400 a year. Just having a document that says you finished high school means an extra $7,000!
If you stay in school, you can make more money. A person who goes to college and gets a bachelor’s degree can make an average of $52,200. With a master’s degree, he or she can make about $62,000. And studies show that if a person gets a PhD, he or she can make $89,000 or more a year.
Of course, people with different occupations have different salaries. If you want to work and make more money, spend more time in school.
