That Medtronic is taking advantage of a huge hole in the tax code which allows companies to basically hide money in foreign countries if they are headquartered there (I am not sure if this is the right language, but bear with me). Basically, the reason they do this is because it costs companies money to bring the money back in the US. It is taxed in the country of origin and then again when it is brought in the US (though it sounds like it is more of a differential - again, I am not clear on the details)
This is one of those times that "the details" are important, and you can't really evaluate the argument in a meaningful way without at least a little understanding of business taxation.
[dayjob]"The details" are that the US has damn near the highest combined corporate tax rate in the world (and literally the highest in the developed world) and yet an incredibly low effective rate after incentives and credits. This means "playing the game", lobbying, mining for loopholes, and creating innovative new ownership structures and theories of tax treatment in the US are more essential to corporate profitability than anywhere else in the world. Given that, why wouldn't you get your firm the hell out if you could? You'll save piles of cash on tax accountants (hi!) and attorneys that don't really add value to the business so much as prevent it from being squandered needlessly, and you can invest in projects that you consider profitable rather than projects that you consider likely to win a tax incentive from the jurisdiction being invested in. If you could either jump through hoops and not run your business, or run your business and not jump through hoops, would you have much trouble choosing?
"The details" are that the US has this asinine concept of "
worldwide income" which I just learned we share only with Eritrea. If you're British and consume no British services and you live and work in France, you don't owe British tax; not so with American individuals or 'American companies'. If you're American, your
income from whatever source derived is by default taxable. It's backasswards and doesn't match the economics of an international world, where a cursory search of the most
dyed in the wool American companies reveals they make two thirds of their revenue
or more abroad. And that's to say nothing of its effects on American's willingness to emigrate and others' willingness to immigrate here. It's mitigated somewhat by tax treaties and the foreign earned income credit/exclusion, but that just adds to the compliance burden (detail #1) further.
"The details" are not that companies are finding the unintended consequences of tax law in the vast majority of cases, a reasonably good test that I see you came back to later in the thread. Take the
patent box, which is pretty controversial over on this side of the pond. How could it possibly be an unintended consequence of the law that companies would relocate their intellectual property to Britain? That's the
entire reason they lowered the tax rate on patent royalties!
Financial Times describes Ireland's tax rate as "a pillar of Irish development policy"; not many pillars are erected by accident. Generous tax concessions are the exact same thing as declaring your country
open for business! The government wants more savings for retirement and more hiring big businesses, so it puts provisions into the tax code to provide for both of them. It's not even an apples to apples comparison - there's just one apple.

Nope nope nope nope nope. This idea needs to die out because it's bullshit.
