Three devastating wars on its territory, three costly invasions and proxy wars, the Cold War, two particularly brutal dictators. Plus, why do you say it failed? The Soviet Union was the second greatest power in the world for about 40 years all of it after being formed around a weak and backwater power that was Tsarist Russia who lost its last war in a devastating manner. The idea that the USSR was a "failure" is a bit reductive. It didn't survive. The regime collapsed, but it accumulated enormous success and the current modern-day Russia owes its strength and power largely to its Soviet heritage. Was the system a failure, yeah it certainly failed on many points, but it certainly succeeded in many others.
China isn't a properly capitalist country. It has opened to some capitalist reform, but strongly remains a socialist and authoritarian country where the State controls over the economy is very important. Nor are modern capitalist country operating outside of a mixed system with a lot of socialist element imbedded in it. You are holding on to a dichotomy in world's economy that is no longer pertinent and representative of reality since the late 70's. The socialism of the early post WWII era didn't exist in 80's neither did the capitalism of the 20's in the 60's.
Russia a success?? I thought we were talking about money not conquests. The standard of living in Russia has never been what it was in free countries. How are they doing now?
You are right. China isn't a free country. Their economy is not free. On the other hand, when you establish a stock market, you must allow a certain amount of freedom or that market will not work. If it does not work, they loose that wealth effect economic advantage that makes the economies in the best economies of the world.
God gave everyone a different view to guaranty mankind a larger view than any one person. The economies with the most freedoms will thrive better because more ideas will come out of the freedom. Diversity is a strength.
Is China discovering total control has it's downsides just like Russia. China had times of mass starvation in the total communist state. How are they doing now?
How is North Korea doing compared to South Korea? Which is the better system??
OK. if you got all the money and divided it equally, how long would it take to turn back into what we have today? Take all Mr. Bezos money away and he will just get it back because he knows how to do it.
Ruling and controlling others is one of the petty things mankind holds so dear. Everybody wants to rule the world. If you rule and control, the system is limited to only your ideas. If you allow freedom, you will find an almost infinite number of ideas generated which increases the benefits for all.
Want the controlled system? Move to North Korea. As much as you complain about Capitalism, I think you will complain more in North Korea. Hungry too, I bet.
