By free market, I mean the idea that, assuming perfect competition, a free market economy would be allocatively efficient By sustainable, I mean that, assuming the market stats of perfect, it will remain perfect in the long run. Not about environmental sustainability. By perfect, I mean that the market fulfill a number of conditions in particular A large number of buyers and sellers My background econ 101 and 102 Let's say there are 1000 sellers in a market. All sellers starts with the same amount of capital customer base, but with they are running with different efficiency. Those that runs an efficient shop would make profit, and those that cannot won't. One by one, the least efficient shops are dropped off the market due to healthy competition. After a while, there are only few sellers left, let's say less than 5. Now the condition A large number of buyers and sellers is not fulfilled anymore, and the market is not perfect anymore. Therefore, a perfect market is not sustainable. I think I have an empirical backup for this. There are many market which takes the form of either monopoly or oligopoly. Oligopolistic markets include aircraft manufacturing, credit rating, processed food and drinks, confectionery, CPU chip sets, graphic card, and OS Monopolistic market includes Microsoft, Monsanto, Walt Disney, and Google I'm not sure if there's a solution I would be very interested to hear one , I'm simply saying that Free market is not sustainable . gt This is a footnote from the  moderators.
