As long as hey are not subjected to double taxation.Some of those countries where they compete in have very mean KRAs. Eg French President Hollande wants to tax top earners 75% tax rate so if you earn 1 m they swallow 750,000 and you remain with only 250,0000.How now?
It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt...
