Why are taxes too low rather than spending too high? I'm perfectly okay with someone arguing either position as long as it's in the editorial/opinion section and not in economics/politics/etc. It's possible I missed it, but I did not see the original article flagged as editorial. Is "The Conversation" an opinion only source? Or is it supposed to be straight news? I guess that would change my mind.
