If there is no lazyness then how to explain the gazillion public debt which we're observing now?
After that I would like to see your ideas why the USSR government borrowed a ton of money from the central bank, while experts were opposing such practice and claimed that it leads to cataclysmic collapse.
Greed of the people currently in power and different interest from yours. Why would the public debt be a problem for anyone but the public? Governments have no reason to reduce this debt that allows them to make harder policies, steer taxes to there pockets and increase the influence of their businesses.
Just give me a reason for them to NOT increase the debt.
USSR mismanagement is far too wide to give a precise answer here, what period do you talk about?
