Now you're into straw arguments and have continued your lies. There is no sales going on here. There is nothing to buy. There is no way to buy. You keep repeating that even though anyone with an IQ above room temperature can clearly tell there's no way it's a sales scam because there isn't a sales process even taking place. Now are their ex pat scams? I'm sure there are. There's scams for EVERYTHING. There's scams for "affordable living" in the US all over the damned place. Seems paranoia is among your list of psychoses.
And how arrogant of you to for whatever mental delusions you have in your tiny brain think people haven't "thought twice" is a window into your arrogantly ignorant mind. Every ex pat I've ever talked to thought two, three, four, five times. Almost all of them moved for a limited period of time to try it out without selling their homes in the US. Many of them tried 2,3,4 different places, different countries even. The idea that you are the only one who ever thinks twice about something or the only one who understands the concept of "greener grass" speaks so much to the volumes of your illiteracy on this subject.
I have literally never seen someone so interested in a topic yet so unlearned about it. Well, actually one other time. It's a mental disease. I pity you.
