Perhaps the one clear message I remember from my college economics class was the concept of “opportunity costs” — for every penny you spend on something, you sacrific the opportunity to spend that penny on something else.
From an Op-Ed piece in the New York Times:
“…the money spent on the war each day is enough to enroll an additional 58,000 children in Head Start for a year, or make a year of college affordable for 160,000 low-income students through Pell Grants, or pay the annual salaries of nearly 11,000 additional border patrol agents or 14,000 more police officers.
“He did not choose wisely.”
