How did Gorbachev's policies of Perestroika (economic rebuilding) and Glasnost (political reform) contribute to the collapse of the Soviet Union?

The policies were very progressive which was against the system of the soviet union. Glasnost enabled transparency and press freedom as well as other human rights freedoms, while perestroika introduced private ownership and other economic reforms. These reforms enabled people to turn towards the capitalist system of values instead of a communist one and to change the government and protest and things like that.
