Are you for or against free trade? That is to say, freer than now. Forget about whether it is free now or not, which is a different question.
Less restrictions or more? Allowing me to trade freely with someone of another country?
I will answer that by saying since free trade is just a textbook theory I don't know. If you ask do I like what we have - no. Do I want it to continue as it is - no. Do I want it to get worse - no.
But when you can show me how free trade works, I can answer you question. Until then, it is only a theory. We haven't see any.
And I like Walter Williams also - but I don't think he has much of a sense of self-preservation - he gives his wife ironing board covers for a presents!! A little attempt at humor - but he said so himself.
