1. I want to buy all books on Amazon.
2. Amazon won't sell all books, therefore:
3. I won't buy any books on Amazon.
I've honestly never before read a serious article that (a) raised such a trivial, entitled complaint about a company, and (b) responded to the complain in such a self-destructive way.
And a monopoly? There are many places where I can (and sometimes do) buy books other than Amazon.
They're using the same tax regime that's been in effect since the heyday of Sears, Roebuck (and yes, retailers whined about it then, too -- it even went to the Supreme Court).
Amazon pays sales taxes in every state where it has a physical presence. Just like every other business.
Do you think Random Penguin, Hachette, etc. pay taxes in your state? Unless you live in New York, no, they do not.
