Re: US GDP
Strangely enough, no, that's not quite how it works.
We don't know how they're handling their sales in China yet, we'll need the dull annual report to see that probably.
"Apple takes US consumer's money and sends a small fraction of it to China to make the thing, an even smaller fraction to Cambridge for an ARM license and sticks the rest of it in Apple's offshore tax haven."
That's true for everything they sell outside the US (maybe China, we don't know). But it's not true for the US. They don';t take those foreign profits into the US, this is true. But the ones they make in the US they don't stick in foreign. They cough up the tax just like good little boys. They are, after all, the largest corporate income tax payers in the US. The rest they then pay out as dividends and stock buybacks.
They've also been very clear that whatever games they play in Ireland and Bermuda they don't play them with US sourced profits. That just gets booked like they're a simple US corporation, pays tax and then gets sent off to shareholders. Their US profits really do recycle around the US economy.
So, your statement is true of the UK consumers money, the German consumers money, but not of the US consumers.
