Free trade without regluations

i was talking to a friend the other day about my blog and trying to get ideas from him, he told me that free trade would be a good idea with or without regulation. Me being my normal self totally objected and said NO! we need regulated trade and he simply said no and explained why. He says that even America has  had little 7 year olds working in sweat shops and doing hard labor while being underpaid, if we want free trade how are we to judge other countries and make them change like we did. Just cause America has changed doesn't mean the rest of the world has to. Plus the more regulated we make trade the harder it is to get other countries to join in.
