I attended a reading of a military historian at my college, he basically said that: "The Sovjets knew the economic clock was ticking in 1970."
It needs to be more drastic than that. They have to reform the companies that were overmanned and under worked. Also they would have to add incentive to get the Soviet workers to work. As the Soviet workers used to say, "We used to pretend to work and they used to pretend to pay us."
