Ahhh, I see your definition. In truth nationalisation really involves the creation of a state owned monopoly which would mean for example, your govt buying every electricity company in the US, lumping them all together and calling it American Energy Inc or similar. What you describe seems to be simply heavy handed remote control.
Out of interest, here low earners pay about 22% income tax and the top rate is 40% even for millionaires - and everyone gets an annual tax free allowance of around $8000 before they start paying tax. How does that compare with the US tax system currently?
We both believe similar things then, but my belief in my fellow Englishmen leads me to trust that their self-respect will allow them only to use entitlement as a last resort, whereas you seem to think many Americans will immediately give up trying if they can get the basics for free.
