Public education spending in the U.S. has nearly tripled over the past half-century while math, reading and science test scores have remained flat.
In fact, Stanford University economist Eric Hanushek reviewed nearly 400 studies on the subject and found that increases in education spending generally do not lead to meaningful improvements in academic outcomes.
Pouring more tax dollars into a school system that does not produce better outcomes is obviously a waste of money. You wouldn’t invest in any company that tripled its operating costs without improving its product in 50 years.
