I would say USA, Canada, Australia, NZ, UK, Ireland, France, Spain, Portugal, Germany, Austria, Switzerland, Belgium, Netherlands, Luxembourg, Sweden, Finland, Denmark, Norway, Iceland, Greece, Hungary, Czech Rep, Slovakia, Slovenia, Croatia, Estonia, Latvia, Lithuania, Poland, Israel, Japan, South Korea, Singapore, & Argentina & Chile to be precise
I wouldn't really consider it a geographic term (at least not these days) I think it's a mixture of similar ideologies, high living standards, education, general high development, GDP, power, military, infrastructure, production, health, etc ,that varies from country to country, but I'd says that list is pretty much the awesomeness. Fingers crossed China doesn't kick our human-rights enforcing buts in the near future.
