>Communism tends to be technologically backwards,
Hardly. Just about all communist regimes in existence rapidly progress. Perhaps none of them reached the levels of the US, but none of them started at the same time either.
When Russia and China became communist, they where centuries behind the west. Under communism they caught up.
Long before the USSR really got a chance to do everything, Germany invaded and nearly wiped them out. They wiped out the USSR, including most of what infrastructure they had.
So the USSR was a new nation that hadn't really been able to work out the kinks of an untried economic system, that nearly got wiped out. Russia still hasn't recovered population wise or otherwise from German invasion in WW2
Also consider this. In spite of all this, they managed to beat the US to the moon, only 12 years after WW2 ended, in spite of all that.
Now, the USSR was a little brutal for my taste, but to say that communism was responsible for them being ass backwards is a blatant lie.
>not rewarding exceptionality, and the tight control over what is produced with the associated bureaucracy.
The US awards exceptionalism. HAR HAR HAR. No it doesn't. Capitalism does the exact same thing. Most large corporations are not run by engineers, but bureaucrats that hate engineers.
Compare to China, where there premier has an Bachelors in EE, with the US who the current president was a lawyer, and the incomming president is a business fool. Most politicians are lawyers.
China is hardly a model of free market capitalism, and their ability to rapidly modernize is due to their very centralized nature.
Even look at the US under its most prosperous period was not the result of a free market. Heck, the internet itself was the result of a very open publicly funded project
GNU and Linux which are most servers. FreeBSD. Apache, nginx, mysql, are all developed outside the typical capitalist model.
