Sadly not that easy. Some countries don’t offer permanent residency at all, some offer it but it requires hoops not realistic for some people like marrying into it, some might have more options but then can be very competitive, and of course many places if you move to you will have to learn a whole new language which is hard for someone passed the critical period. Picking up the language and culture could take literal decades and if you don’t have connections to help you settle in during that time you’re probably not going to have a good time. Also the USA tries to discourage you from leaving by requiring you to submit taxes even if you don’t live in the USA anymore. You can only get out of it by renouncing your US citizenship which would make it harder to visit family. Not to mention up and moving can be initially rather expensive until things settle down. There are many barriers which can be overcome but I would not say it is “easy.”
