You didn’t want to be the guy chosen to tell Stalin that the wheat crop failed or the production quotas on trucks and cars were not met. Why?
Because despots always blame people, not systems.
The problem is that government is not the best means to do anything well. The problem is the absence of two crucial things: the knowledge to assemble the resources properly and the means to make the economic assessment of the value of competitive resources. This is what happens when you eliminate the profit-and-loss system. You can throw massive resources at a problem with the end result being disappointing.
.. The truth is this: Government doesn’t work.
