It was simulated quite good sometimes, though.
Simulations are limited by the minds of those that design the simulation. I make lots of simulations, but I can only put into them the things I mentally am aware of and can perceive. The variance in humans adds a lot of chaos that is not properly represented in simulations. This also makes central planning and quotas difficult to be accurate as well. Yet that is a completely different issue. :)
And because the simulation was always flawed, there never was communism, because communism only is realized when the plans work.
QED ;)
Which can be said of ANY ideology. That is also a person saying MY PERCEPTION of X is the real X and anything not X is well you know... not X.
Kind of a bullshit excuse and argument in my opinion. Also a common one. :)
Like I said every person thinks differently so X is a moving target.
