BOYCOTT WALGREEN'S - 2 things you can do about Walgreen's trying to dodge their US tax responsiblities on their profits they make in ... the US.

I cannot stop them from redefining their corporate residence from the US to Switzerland (evidently that's one right a corporation has in this world that I a human being don't have - the ability to shirk my financial responsibilities), but there are two things I can do -

1. Don't do business with Walgreen's - I can ensure my money doesn't go into their profits.
2. Tell all other humans to not do business with Walgreen's - if Walgreen's wants to avoid paying taxes on their profits, if enough people follow suit, then at least they'll have much less profit to avoid paying taxes on.
