Most of "the market" is controlled by forces I don't feel have my best interests at heart. Corporations, local, state and federal governments all have a hand in "the market" as it reaches me. It's being manipulated every step of the way and it's never going to work for any of us under present circumstances. Individuals have little or no control over "the market" except for handing over their money...supply and demand is controlled and dictated by someone else besides me.
Governments have control over the economy. By definition, they do NOT have control over "the market," since that term means people trading WITHOUT governmental interference. What we have now is not "the market." It's a warped and mangled corporate/fascist abomination. But of course, everything bad about it gets blamed on what FREEDOM still remains.
It's becoming harder and harder to trade in free markets. if you mean buying directly for cash or other forms of compensation. Here locally in Nebraska there used to be tons of farmers markets to buy directly from the growers for whatever you could barter them to accept. The governments put an end to that in an effort to protect Wal-Marts monopoly here locally.
