Billionnaire

I’m watching The Rebel Billionnaire, fun so far. Pretty crazy stunts. I have one question though: why the f*cking h*ll are all the contestants American? Again? British entrepreneur. International companies. Show starts in Oxford, continues in Hong Kong. Why the heck are all of them from the frickin’ US? Nothing against Americans there, just wondering, with an international setup, wouldn’t a more diverse cast make sense. I’m sure there’s the fact that US listeners wouldn’t be interested in an international cast but come on, a mix? Please?
