Do you like to have to bribe your way around the local bureaucracy?
Do you like to live within a mile of crushing poverty?
Do you like to endure social, natural, and economic crises?
If you answered yes to all of these, then yes an emerging market is for you (i.e. Brazil, China, India, etc). If you answered no to any of them, stay in a Western country.
A nice, cozy, Western country like the United States?
If you want to avoid all these, you pretty much don't have other choice than one of those OMIGOD SOCIALIST! wellfare states, and even then these are not guaranteed. Nitpicking aside, all these three problems seem to be a part of everyday life in the US, just in a (slightly) different scale.
