As everyone wants to believe. And by 'clean' I mean, oh we love to pay our taxes... we are a loyal US company... and all the rest. This story above is about Amazon, but Apple and, from another source I have, hundreds of other "socially responsible" firms, participate in the same worldwide tax shenanigans. All perfectly legal... but don't ever think these guys are the 'good guys'.
Those of you ready to slap taxes on companies moving out of the US... be aware the BIG tax money to be collected isn't from them... but from all the "wonderful" US companies who remain US based, but then turn around and hide from U S taxes BILLIONS of dollars! Legally, of course.
So, if you really believe these companies are looking out for your interests... grow up. And stop bitching about all the money not being paid by those nasty corporations... which include many of your favorites.
