Spending on education accounts for just 2 percent of the United States annual federal budget of more than $4 trillion. That total counts all spending for Head Start, federal elementary and secondary services including Title I and special education, career and adult education, and student aid including Pell grants and student loans. That's just 2 cents of every federal dollar invested in education even though public schools serve 90 percent of all students, and the increasing cost of college makes higher education a struggle for many. The federal government invests only 2 percent of its budget in education even though we know that money matters in education -- that every $1 invested in early childhood education saves at least $7 in later societal costs, that students who graduate from college earn more and have lower unemployment rates than those with just a high school degree. Every dollar wisely invested in education makes sense. Helping students of all ages achieve and succeed makes sense. Supporting them by increasing the federal investment to five percent of the budget makes sense.
