Every cheap country (Vietnam, Nicaragua, Thailand, Bali, etc.) will have a hodge podge of backpackers, ex-pats, retirees, etc. Enough locals will speak English to support providing necessities and socialization can happen with the other ex-pats.

Working there is a different story, but generally you don't want to work there since the reason they're cheap is that the people are poor. The local jobs are low paid. The trick is to be able to work remotely or more rarely as a well paid employee of a foreign company.
