You must not be from a former communist country. The system worked for two-three decades during the initial industrialization phase. When that phase ended growth was hard to find (the whole system was based around factories and moving villagers to cities). That's when the numbers started going down and the system started faking numbers to give the appearance that all is well and nobody could disagree with them.

At a country level (not talking about Amazon) these systems are fragile and don't handle volatility well.

Re: Amazon - you can't compare countries with private corporations.
