Name and describe three significant problems that the economy of the soviet union ran into in the 1970s and 1980s

In 1974 there was a power summit meeting near Vladivostok, U.S.S.R. between President Gerald Ford of the U.S. and Leonid Breznev of the Soviet Union. After the meeting Breznev went to his waiting train. The train however did not depart. The journalist and others who traveling on the train with Breznev were not told the reason for the delay even though the delay extended through the night. The next day they were told that Breznev had suffered a stroke. Breznev's personal physician, Mikhail Kosarev, said the problem was an overdose of his sleeping medication rather than a stroke. The symptoms were similar: slurred speech and muscle weakness. Kosareve said that if effect Breznev was a drug addict during this period and had merely miscalculated his dosage. It was not uncommon for the top leadership in totalitarian states to be addicted to sleeping potions. Mao and the top leadership of the Communist Party in China had been addicted to sleeping pills by the time of the Long March. Totalitarian leaders have a hard time relaxing and getting to sleep.
