Potato chips: A symptom of the U.S. R&D problem
Last year, U.S. consumers spent $7.1 billion on potato chips — $2 billion more than the federal government’s total 2009 investment on research and development. There’s something wrong, here, when Americans are more willing to empty their wallets for the junk food that will swell their waistlines than for investments in the engine driving the creation of jobs, economic growth and national security.
