 Ryzhkov's Plan and The 500 Days Programme were broadly similar, with both supporting price liberalisation, decentralisation and privatisation. The main difference between the two was Ryzhkov's desire to retain much of the social security system, free education for all and the continuance of a strong central government apparatus. The 500 Days Programme did not mention political union with the other Soviet republics, but instead weakened the authority of the central government by establishing a market economy. In other words, they left the question of continuing or dissolving the Soviet Union open. On 17 September in a meeting of the Supreme Soviet of the Soviet Union, Gorbachev openly supported the 500 Days Programme, claiming it would not lead to the reestablishment of capitalism, but instead to a mixed economy where private enterprise played an important role.
