It's also easier with a largely mono-culture in a relatively small population/area that is inclined, socially and historically, to work. Contrasted by say USSR, China or other communist societies where it's largely forced and the people are largely, effectively slaves. Although that work first culture is coming at the cost, to an extent, of a waning family unit.

It's a bit of a mixed bag that's much harder to implement at a larger scale. If the US split up into separate states, much more loosely joined like the EU or original confederate structure before the constitution, each state would stand a better chance at such a system.
