political reason is that more or less important decisions in all areas of the Soviet republics were made in Moscow, even though each republic had its leadership.The incompetence of the central office, the reluctance to pass the Republican administrations of the government led to the ineffectiveness of control, loss of time and resources, to the discontent of the population and the leadership of the republic.
in many republics in the wake of Gorbachev's democratic reforms there and acquired the force of centrifugal nationalist tendencies began to emerge ethnic conflicts, to strive to secede from the USSR and the independent development of th
e country.Many internal national conflicts - Nagorno-Karabakh conflict, the Transnistrian conflict, the Georgian-Abkhazian conflict - are closely linked to the aspirations of national self-determination and self-government.
economic reasons lies in the disproportionate development of the national economy.The arms race, the space race, the war in Afghanistan, an endless assistance to the countries of the socialist camp demanded more cash investment, which was reflected in the production of consumer goods.The military budget exceeded social 5-6 times.Maintenance backlog in the civil industry has long been apparent, and as the years increase.Economic disparities are expressed in inequality of Soviet republics in terms of shortages of goods and development of the shadow economy
CCCP Gorbachev's reforms not only led to positive results, but even accelerated the collapse of the Union.As already mentioned, the democratic changes have led to national tensions.Trying to reduce the technological gap with the help of a set of measures called the "Acceleration" failed because of the weakness of the economy of the USSR.
majority of consumer goods produced in the Soviet Union, were of the same type, simplified to the extreme, made of cheap materials.Production efficiency measures the amount of goods produced, quality control has been minimal.All this, together with periodic interruptions of food and consumer goods, with various prohibitions and restrictions, along with a constant standard of living behind the West gave rise to the Soviet citizens' dissatisfaction with the socialist way of life.
next reason - artificially created "iron curtain": difficulties with going abroad, even in socialist countries, a ban on listening to "enemy voices", difficulties in acquiring high-quality imported goods, a strict ban on the operationcurrency.All this, together with the failure of the economy of the Union, has given rise to strong growth of the shadow economy - the clandestine manufacture and sale of various goods and services.
strict censorship in the media, the withholding of information about internal problems in the Soviet Union and about the life of the western countries, a ban on the publication of a number of works unknown facts of Soviet history, suppression of information about man-made disasters - all amplified informationUS war against the Soviet Union.
