No one can answer that question for you, except you yourself.  People's tastes and requirements are all different.

Do you speak any other language than English?  If you don't speak Spanish you will have difficulties in most Spanish-speaking countries just in your day-to-day life - and never being sure what people are saying, if they're overcharging you, or even planning to rob you.

If you don't speak the country's language really well, you could find it difficult to impossible to get a good job - good jobs are scarce in most countries.  Teaching English is a possibility - but most people who do that do not earn very much.  If you don't need much, though, that might suit you.

You could certainly visit several countries to see what you like and don't like, and then go from there.  Most countries you can stay 90 to 180 days as a tourist and just travel around.  You can always "bum around" on very little income - that way you'd certainly see many of the bad points in a given country, but you might also find it's a good learning experience.

You'll be hard-pressed to find anywhere where life is as easy and convenient, and where you can make as much, as in the USA.  Most people who become expats speak the language to some degree, and have some means of income, whether it be a retirement pension or a job they can perform remotely, or if they can start a business - and for most of them, their income is far above most locals which goes a long way to making life enjoyable there.

If you do find a job and earn what the locals earn, you are likely to be quite disappointed with the lifestyle that will buy you.
