Question; What is free about the Free Market?

A Question to all you well educated people out there especially in the Free Market. What is free about the Free Market? Manufactures and Farmers limit production to drive up prices, fix prices to maximize profits and keeping any one company from becoming a Monopoly there by bring down the government Sherman Antitrust Act on them. Plus the many rules put on both Banks and the Stock Market to keep people from losing too much of their money there by damaging the economy. So with all this in mind should the government have more control over the Financial Systems to protect the working and middle classes?
