One of the reasons for the collapse of the USSR was the delay in carrying out reforms and restructuring of the planned economy.
According to him, the collapse of the Soviet Union was caused by the last decade of its existence.
The USSR was not ready to reform its economy, which was losing efficiency just every year. And the so-called economic stagnation of the 70s was a prologue to the fact that the Soviet Union ceases to be economically interesting, will cease to be the center of attraction, the growth of living standards.
No one predicted the collapse of the USSR. It was supposed that there would be some kind of transition from the plan to the market, and even wrote scripts. But that this will happen in the conditions of the collapse of the USSR.
