You should read some real economic history and forget the Crank version. There have been very few periods in history wherein capitalism was as pure as you believe either morally or nationalistically. Government has almost always been intimately involved in economic events and business has always been seen as “greedy”. But Adam Smith showed that good intentions are irrelevant to the success of the economy. The only requirement is that a business legally provide a product for the lowest price possible. THAT is its job.
I am pleased to see that you believe free trade is good and dismiss the anti-free trade tirades of others here.
Our economic system now is not as free from regulation as one would wish but it is still the most productive in the world and IF the electorate becomes pro-business and rejects the socialist crap it is taught then there is a chance for it to return to glory. But that is apparently a long way off given the discussion on this thread.
