For instance, the label predicted for this Reddit comment(*) was
Economics (but it appeared in the Technology subreddit):
This is why we codify our laws, so that your opinion of okay doesn't define legal. Not saying mine does, but
when we get together and codify things, at least we let everybody know this is our low bar for okay. Google's
motto is not "don't break the law". I believe that a companies contribution to our (US) government in the form of
taxes is a poor criteria for judging of evil-ness. Unless they're notably dodging taxes, that is. Enough so to be
distinct. And that doesn't take into account how the Irish, Dutch, and Bermudians feel about large corporations
setting up head quarters in their countries. Clearly these people decided that if they lowered their taxes, more
companies would come to them, leading to more jobs and revenue. While we (US) decided that we should raise
the taxes to increase revenue. It isn't like Bermuda just forgot about raising their corporate revenue tax. And
that's why countries like Ireland and Bermuda have so little to offer their citizens. Is that why Ireland is the UK's
economic powerhouse?
