We’re talking about the bigger picture, in which the people gave the nod to this evil regime because it was serving up their bread and circuses.
And now that its inefficiency has made everything scarce, why of course it is going to look out for itself first. However even yet they are not a total omni-police. The people are in a stupor and in psychological enslavement to it. In longer term communistic situations like Russia, the people learned various coping mechanisms.
If the waste would stop, the inadequacy would probably cure itself rather quickly.
