Pick out the most simple product and try to tell people how easy the free market is. Not sure this is helpful.
There are 3 things why I don't believe in a REAL free market:
The free market is no model to run a economy. It's just price finding via demand.
Sometimes I think liberalism expects too much of it.
The free market don't serves the people/country/society. It doesn't considers social security, national security or a long term business model.
There is no strategic element behind it. The long term thinking is done by the CEOs. And I don't believe in this poeple since there too many MBAs and only few entrepreneurs in the system.
Things like the shareholder value make it even worse.
You don't understand a modern market. We've seen it in the crisis. Especially the financial industry has become too complex to understand for economists and the business people who run it.
Since I highly doubt that the governments will change that or even understand it to create functional regulations, I think the tools of today are simply outdated. I think that the MBA of today is almost worthless since it doesn't give people the right tools to analyze the market. Forget Porter, learn kybernetics. Modern tools of system analysis is the key. For the market and the company.
The third point is that main target for a company in a free market is to eliminate it's competitors.
So the market itself is in a suicidal mood.
Friedman had some good points. But I think he would have rethink some of his theories after 2008.
