Lived in the US throughout my 20s, lived like a grad student (with a few splurges here and there to celebrate career milestones) and saved+invested most of my money earned during a FAANG career, during covid i bought+restored an old manor in a rural area in my home country where I can live on a few hundred euros a month (it blows my mind what 30 euros gets me in fresh produce from local farmers compared to $100 at BiRite in SF). I'm still ~40 minutes away from a mid sized city and airport that directly connects me to large cities in Europe.
It's been worth it although it's come at the cost of personal relationships somewhat.
