Don’t fall for any kind of “public vs. private” scam. These are infinitely mutable terms with no objective content, but which are used only for the purposes of power.*
For example, conservatives claim to want small government, but they really want ever bigger, ever more aggressive government. They claim to want less taxation and regulation, but they really want ever more crushing taxation and regulation. It’s just that they want government to function only as bagman and goon for the 1%, and want all taxation and regulation to be of, by, and for the 1%. Their favorite mechanism is to shift power from nominally “public” government to nominally “private” corporations.
But corporations are nothing but artificial extensions of the government. Government artificially creates them in order to shift government power to them. The nominally public entity then serves as bagman and goon for its private extension. But everything remains one holism of power and aggression. Taxation is taxation, whether imposed by the nominal public entity or the nominal private one (for example, banks charging us for access to what should be our sovereign money; similarly, there’s no difference between a public park or private club charging admission fees – both are charging we the people for access to our land and recreation). In the same way, regulation is regulation. For Monsanto to force farmers to buy stacked genes they don’t want in order to get the one they do, or for banks or telecoms to force one to accept all sorts of pricey ornaments and gotcha fees in order to gain basic service, is the same as the government forcing us to jump through every kind of hoop in order to also gain its allegedly necessary services.
The best way to cut through all the lies is to ignore the words “public” and “private” and instead simply see where power is concentrated. There, by definition, is the government. Anyone who wants power to concentrate anywhere wants big aggressive government. Anyone who wants any kind of centralized, top-heavy hierarchy wants big aggressive government.
