The same statistics that say China's poverty is reducing claim that people under Mao lived in poverty. Poverty is defined as lacking basic needs, and while Mao-era China was still relatively underdeveloped, the people were not poor because they got basic needs met. Deng Xiaoping commodified things that used to be decommodified, ended subsidies for goods, and overall caused inflation of most prices and a decline in wages. Speaking of wages, Deng re-commodified labor-power, and now China has a higher unemployment rate than the US; what sort of socialist society has the purchase and sale of labor-power?! Commodity production is inevitable in underdeveloped socialism, but there are also plenty of de-commodified goods and services; the capitalist-roaders eliminated them. If you're not a fan of Khrushchev, you cannot support Deng.
Capitalist production is the highest form of commodity production. Commodity production leads to capitalism only if there is private owner-ship of the means of production, if labour power appears in the market as a commodity which can be bought by the capitalist and exploited in the process of production, and if, consequently, the system of exploitation of wageworkers by capitalists exists in the country. Capitalist production begins when the means of production are concentrated in private hands, and when the workers are bereft of means of production and are compelled to sell their labour power as a commodity.
