Question about US trade policy

I have been following this issue for a time now and at first I thought that free trade agreements would be beneficial for the US population and the rest of the world. But as time has past my notion that free trade would has benefited either the US or undevelop nations has change. I thought that with free trade there will be more jobs but the reality is that many jobs have been outsourced especially in the manufacturing sector and that undevelop countries will see the type of progress which will get many people a decent living, this has not happen either. All I see in my opinion is that the corporations are the one benefiting from the current US trade policy.

Should we give up on Free Trade altoghether?Modify it somehow? Leave it as it is? What should be the next step in US trade policy?
