hugo,
We have all gone around and around on this before, but the USSR being the "poorer country" was only a part of the issue. Since the 1930s, the underlying economy of the USSR had been geared to military production. That was both because of the distrust and somewhat paranoid fear of the "West," and also because it gave the population jobs.
Lacking extensive consumer driven industry, the economy of the socialist state was an imitation of what the USSR purported to be their nemesis - the fascist-capitalist West. The West produced arms, but it also produced consumer durables and housing and bank deposits and agricultural surplus. The USSR produced arms and vodka. Insufficient wealth was produced that could be accessed for all that the Soviet military state wanted:
A 4,000,000 man standing army with conventional superiority in Europe.
Superior missile forces.
A navy that could contest the US anywhere it could go.
Something should have gone but nothing did. The Soviet military state never could understand that it was a continental power - and secure in that it could not be successfully attacked. They spent it all on a lot they did not really need, and could not help themselves.
