That quote has it backwards. The farther left a government moves, the more completely it controls the lives of its citizens (subjects? slaves?). Every government must legislate what people can and can't do, to some degree. (Whether an individual agrees with particular laws or the given reasons for them is another matter.) Even a libertarian government has to have some agreed rules on national and personal security. A conservative government adds additional rules regarding issues of mutual benefit, such as utility and transportation infrastructure, etc. It is the left-wing government that wants total control, wanting to tell people not only what they can and can't do, but what they can and can't think (thought crime exists in countries like Canada and Sweden).
Every socialist government despises people and thinks they have to be 'managed': 'you suck, so we, the Omniscient and All-Beneficent State, will manage your money/health/education/ideas/opinions/... for you'.
Isn't it strange that every truly socialist/communist government has disintegrated? Must be something to that free-market stuff after all.
