Some countries have a working vacation type of visa, but most of the jobs you'd get with that arent going to pay super well and are intended on covering your living expenses while travelling.

and it would put me on the path to a better life than I would have in America

If you're intending on immigrating, many countries have pathways for taking higher education and getting permanent residency & a career after you graduate.

There's also specific industries that countries may give you a work visa and a pathway to immigrate (e.g British Columbia, Canada is trying to acquire healthcare workers from the US).

Edit: There is also the option of remote work, however I think many companies are moving away from this as times change.
