The discussion was about tariffs, not free markets. Free market labor in the United States, with its emphasis on humanitarianism and the resulting legally binding and sometimes costly restrictions necessary to enforce the principle, cannot compete with other countries that virtually employ slave labor which dramatically lowers cost.
Tariffs are interference with the market economy. The free market economy is defined as the market economy FREE from government interference. So when you are talking about tariffs, you ARE talking about interference in the market economy.
I thought you’re initial reply was a good-faith question sincerely looking for some input from me. But now it appears all you want to do is argue a point you’ve already settled on.
