The total cost of the entire program over its projected lifetime is $1.7 trillion. The F-35 is made by one company, Lockheed Martin (with some pieces made by a couple others). This entire program is a massive transfer of taxpayer money into one company.
Another data point is that it's estimated that all student debt in the US combined is $1.7 - 1.8 trillion.
No wonder America keeps falling behind.
