You're in favor of free markets? So you're in favor of one company ruling the world then?
Yes I'm in favor of
FREE markets. FREE meaning that there is not a government body that can be hijacked and used to grant and maintain monopolies. All of the things which lead to monopolies in a capitalist system are entirely due to government.
If you'll read any of the material I linked to, you would start to understand what ALL government is. I don't care if you want to call it Socialism, Communism, Fascism, etc. Those are bullshit ideals that all stem from the same fundamental belief. The belief that the use of coercion is morally acceptable. Socialism is a forced redistribution of wealth through various methods such as taxation, tariffs, and subsidies. It violates private property (your right to the products of your labor) in the same way that all government does.
Now please go ahead and explain how one company (without using government) would rule the world.
It's incredibly easy and it's already happening!
Look at Google! Look at the food industry!!
If government does nothing, then one company (the best) will get bigger and bigger. Then it will slowly absorb any concurrent company or destroy it! In a FREE market as you say, the best company will continue to grow until nobody can get it down. And then it will have a complete and absolute monopoly.
The food industry is currently only 6 companies when it was still hundreds if not thousands only a few decades ago. American banks were dozens, now only 5 of them control everything.
Free market has only one consequence: concentration of power and wealth in a few companies. The richest get richer, the poorest get poorer.
If you don't mind living in something like this, go on and live your American dream.
