Essay on free trade.?

Im currently writing an essay on free trade and I wrote my other paragraphs and im stuck on the intro. It needs to include
-hook- to get readers attention
-bridge- connect hook to thesis
-thesis- what my paper is about 1 sentence.

My imagination has run out and I cant think of a good hook. Any ideas?
