Sounds good on the surface except you can't actually spend any meaningful amounts of money in your home country.
"Sorry Mr. IRS auditor this big mansion I live in and these fancy cars I drive are all owned by my corporation. I make 80k a year and I paid taxes on that already."
Good luck with that!
You are correct! (I think)
I mistakenly assume that people have the same thought process as I, where my aim is just to stack cash somewhere with no real desire to buy mansions and sports cars, and being a permanent expat makes the process easy.
