You can always move to a town in Greece, in the mainland (something smaller than 5k people), close to the beach. You can live amply with 20k euros per year (about $22k) for you and your spouse. Buying a house is about $100k to $150k, taxes are rather low for most professions, and you can have your own vegetable garden, trees, and chickens. Fresh fish, goat meat (best kind of meat for humans). Car repairs and other repairs are much cheaper than in the US (my husband was expecting a $2500 bill to replace the car engine’s chain, and it was just $600).

If you’re in your 30s right now, and you’re going to live until you’re 100, that’s “only” 1.4 million euros. If you get a couple of kids, that’s 1.8 to 2 mil euros. Definitely not 20 million though.
