Original sentence: After Mikhail Gorbachev came to power, he began a process of economic liberalisation that moved the economy towards a market-oriented socialist economy
Edited sentence: After the mentioned ill-fated policies were put into effect, the economy not only did not improve, but declined into disaster by the end of the Union (1991).However, this is not the main reason behind the dissolution of the union, as stagnation did not prevent it from continuous (albeit slow) economic growth.The economic stagnation that the Soviet Union was suffering was caused by poor governance under Leonid Brezhnev and inefficiencies within the command economy.The main cause of its dissolution was behind the economic reforms mentioned above brought by Soviet leader Mikhail Gorbachev, as these reforms caused a complete disrupt in the soviet economic model and were doomed to failure.These factors contributed to the final dissolution of the Soviet Union in late 1991.When Mikhail Gorbachev came to power, he began a process of economic liberalisation that moved the economy towards a market-oriented socialist economy.When the stagnation began is a matter of debate, but is normally placed either in 1973 or 1975
