1.
The relative overemphasis of military support vs. economic needs,
particularly in Russia proper but also endemic to the Warsaw Bloc as a
whole.
2. The relative economic collapse of the Soviet collectivist system proper.
3. The military/economic impositions placed on the "Warsaw Pact" nations
by the USSR, in contrast to the Marshall Plan and similar policies
implemented shortly after WW2.
4. Chronic and systematic central planning in a command economy (economy
by plan) contrasted with (economy by the people) where self-interest
dominates the economic course of events vs. necessarily state-interests.
5. Lack of infrastructure and economic reinvestment - this is a problem
for every major economy but in the old Warsaw bloc states, deteriorating
conditions did not allow for the agressive reinvestment over time.
