What kind of country is Monaco with the largest resident population?

Monaco. I go there to watch car races every year. This is a very beautiful place, with castles and close to the sea. There is no need to pay personal income tax before hesitating there. Many rich people in Europe have emigrated. When you go there, you will often see all kinds of sports cars, because rich people in Europe will often go there for holidays and have fun in casinos there.
