I wonder, can one (such "international rented person") make a living out of such business?
It's not anything new, it's just that more people have caught on and jumped into the game.
If a musician or dancer, two roles mentioned in the article, then making a living out of it is the definition of success!
I've also met some non-dancers non-musicians that do it full time. But less misrepresentation, more connection to a career and as a consultant. For example, a chef that visits restaurants when they're opening; while not famous, gets his photo taken enjoying what he's doing.
So, back to teaching English I guess :-)
Manufacturing proof that "pretty women like men who own this" sounds like a winner, honestly.
