You are astoundingly correct for a moron, as you have four words correct out of six. That's nearly 70%, or a C average. The correct answer is:

LABOR BUILT THIS COUNTRY. Period.

However, unions are destroying this country, because they represent ANTI-labor. Name me one thing about a union that actually promotes labor. Name me one thing a union represents, which is aimed to help the company which employs the union workers to be productive and to encourage production. Unions have destroyed the auto industry, the steel industry, the education of our children and most city, county and state budgets across this country.
