Liechtenstein, along with Monoco and Switzerland are the dedicated tax-free banking havens for the rich of Europe.
As soon as a few million are made, they immediatly buy property in one of these countries and declare that all future income be paid through those banks.
Pro-athletes, celebs, major business people.
Example: The F1 race car driver, Lewis Hamilton, who recently nailed his big payday contract and is endorsing products like crazy claimed “the paparazi was just too mean to him” so he was going to be relocating to Monoco.
And considering in many countries like England and Germany, over 50% of your income goes to taxes, I really can’t blame them.
