There is not greater organized evil than free-trade. Here trade is also used for reinforcing and supplementing the economic self-sufficiency. But it is used as a peripheral and complimentary measure and not as the central part of the economic model. Plus trade has to be subjected to checks and balances so that its expansionist traits are inhibited and subdued. World knows it only too well that most of the dehumanizations and slavery of entire class and race of people have come through the route of traders.
Man is more than economic animal.
People end up spending their entire life in preparing for economic life and pursuit of economic life and even at the end of such hectic life, the sum total of their wealth barely cover their old-age. Sum total of their economic activity at the fag end of their life turns out to be a big zero and so is the sum total of their non-economic pursuits. They have nothing to pass it on to the next generation who must start from big zero-line and repeat the cycle all over again. This is the complete dehumanization and devaluation of life and humanity. Under trade-based economic model, nobody is a winner.
