Libertarians promote anarchy and hope for a Utopia with no government. If they ever achieve it, it will resemble a Wild West dystopia more than any place I’d like to live. No Government, no Law, no Safety.
Marxists talk of a workers’ Utopia where the government withers away, but the track record for Socialist Governments, once elected or installed after a bloody revolution, is to put in place a totalitarian dictatorship where the individual has no freedom and is enslaved by the State. Hitler, Stalin, Mao, Pol Pot and the Kim dynasty have all done the same. Marxism is based on the false concept that an economy can be run by Government bureaucrats through central planning: this will not, and can not ever work.
Capitalism is the only system that creates new wealth, and has lifted billions of people out of poverty. Extreme unbridled Capitalism could potentially do evil things to the environment or to people for the sake of profit, but ethical Capitalism is the way of the future. The best we can hope for is a World where Government is only just big enough to enforce ethical standards in business, but not big enough to interfere unduly in the laws of Supply and Demand. Ethical Capitalism can be seen in businesses that foster diversity and fairness in the workplace and encourage their staff to volunteer for the good of the community.
That way the Libertarians get a smaller government and lower taxes, while the Marxists get Social Justice without running the country broke through idiot socialism. It is win-win and is called Less Government. This is the compromise between the extremes of Libertarian No Government Anarchy, and Socialist Totalitarian Dictatorship.
