First off there have been many variables that affect the future price of similar goods, and I don't think it's fair to say if it werent for Free Market things wouldn't be cheaper. Yes I think free market accelerated the process and helped to make it low. However, with or without free market the price would have went down as they perfected the technology in making it. Perhaps that would take longer without the free market, but the price change is not 100% the free market.

I am very pro free market, I'm also anti-monoply, it sounds lame to me to punish people for being to good, but it's worth it to me advance and accel society faster. Lastly, the point of the free market isn't lower prices that's more of a side effect, it's more to allow a situation that each person can open and operate their own goods while trading to make advantages for themselves as they please. I think that at its core is the goal of the free market.
