Finding moral companies that doesn't do unethical things to avoid tax is not hard.

I'd claim that the absolute vast majority don't.

So how would I go about determining whether a company I want to buy from doesn't do unethical things to avoid tax? It's everywhere and nowhere.

For larger companies it's just a cost/benefit exercise - there are professionals and an industry built around making and executing these decisions. If the rewards are large enough, they'll do it. How can I, as a consumer, work out if Apple is paying the correct tax on the app payment I make in the App Store?

But equally not all tax evasion is on the scale of Apple's. There is plenty going on at the other end of the spectrum. How can I, as a consumer, work out if my local window washers are paying the correct tax on their cash payments?

I would argue it's virtually impossible for a consumer to establish these facts. And that's the way it should be - we ought to be able to rely on specialist agencies to enforce the rules.

You probably don't. But when you come across that information you can decide what you want to do with it.

Well true, it would be unfair to put them all in one basket. But still, there is little use complaining about Apple (I don't usually hold back criticism here). We should hold those responsible creating these laws.

Disagree. I don't think complaining will change apples way but they sure deserve the negative publicity.

If apple wants to be an asshole we should treat apple as one.

That is perfectly fine too.

But you will have to be fair and treat all those doing the same as asshole. Which is pretty much ALL MNC.
