When a company like Apple avoids/evades paying taxes, it hurts the free market by taking for themselves an advantage that other companies can or do not.
No. There is a difference legally between tax avoidance and tax evasion in that the latter is defined to be illegal. What Apple is doing is legal. Hence, anyone or any business in the so-called "free market" can pursue the same strategies.
While the original poster attempted to make a distinction between "legal" and "morally acceptable", it's worth noting that what Apple does is probably considered morally acceptable by Apple. Why should I give the original poster's opinion on moral acceptability any more weight than Apple's?
By not contributing their share of taxes
That's an opinion. Apple doesn't have a defined share of taxes. And I've noticed that no one goes out of their way to pay more taxes.
Stealing is immoral. [...] Lying is immoral.
No evidence in either case that this is occurring.
You cannot make a persuasive argument that you are not represented.
What does "represented" do for me? Sounds like it's nothing more than a pretext for claiming that I have no justification for complaining about taxation. The problem with my "representation" is that it is diluted by a lot of other people.
What I find instead is that I represent my interests far better than any government does or could. Hence, I have a natural desire to see power shifted from that government to me. Second, since government is running so very counter to my beliefs and opinions, particularly on fiscal and future-oriented matters, why should I think I'm being represented here? Instead, I find that those engaging in adventurous tax avoidance seem to further my interests better than the governments which claim to represent my interests.
I wouldn't make the mistake of saying that Apple is representing my interests because they happen to be doing something I approve of. But we seem to have common interests which is more than I can say for the people who are getting worked up over what is supposed to be morally acceptable.
