Krispy Kreme is failing badly in Japan for example. They come to Japan, try to sell their plain too sweet glaze donut against this. They even try to charge more than the competition. They lose.
You are competing against products made by avg 110 IQ people. American products suck by comparion in most cases, and you are too dumb to adapt to the competition. Therefore, nobody in Japan buys your product. What a surprise!
