John Ratzenberger On Why We're Becoming A Third World Country

He gained fame by playing the wiseguy postal worker. But John Ratzenberger, who played Cliff Clavin on the NBC sitcom "Cheers," is nothing but serious now. The actor has found a second career as a social activist. His cause is America's skilled workers. He has advocated for them in documentaries like "Industrial Tsunami" and TV programs like "Made in America," which he hosted for the Travel Channel. And through the Center for America, he has also spearheaded the 10 By 20 Pledge for America, which seeks to grow America's skilled labor workforce by 10 million before 2020. He sat down with AOL Jobs to talk about the cause.
