China is comparable, but further down the development chain. Social safety nets and good governance tempers selfishness a bit, but can't eliminate it (e.g. Switzerland). America has less of a net and equality than much of Europe, which is why selfishness seems to be more apparent there than in Europe.

No, China isn't even remotely comparable. Just a few decades ago, it was a mostly agrarian economy. They've had massive industrialization in a very short time, but they don't the much longer-term culture of industrialization and social programs and worker protections etc. that western nations have.

And how exactly is Switzerland "selfish"? They may not be part of the EU, but they appear to have just as many social safety nets as any other western European nation. This seems like a rather silly charge to me.
