The US has "a" culture?

The export of neoliberalism wasn't the export of a system which was known to work in practice, it was the export of a system believed to work in theory by certain people...south American neoliberalism deliberately went further than was possible in the US...it was an experiment.

nor when Euro Social Democracy gets imported to the US ("Nordic Model"). 

That happened?

I mean, even in the EU it seems very similar tax-and-spend models work well for Scandinavia but abysmally for PIIGS.

Tax and spend isnt a boolean. Everyone does it to some extent.

(don't cheat on taxes etc.) 

Let's say that applies to Greece and Italy. Would it also apply to the US?

One useful way to model is that supra-national, EU-level redistribution does not really work

Is that a fact? Where is the EU's Detroit?
