Tax avoidance is legit ... if the rules allow you to claim a deduction and you do then that should be the end of it. So if, as reported, Donald Trump was able to claim a close to $1b loss that his business empire suffered in the 1990s with the result that he paid no tax for the next two decades then it should be a case of ... nothing to see here, move on.
But it's not like that. He's running for President and there are a hell of a lot of taxpayers out there in voter land who, for a whole variety of reasons, will say that doesn't sit well with me. The 'he's smart' argument run by the Trump camp may be right but the reality is that Trump, in not releasing his tax return, allowed the charge that he had something to hide gather a head of steam and perception became reality and the reality is a negative and right now Trump doesn't need too many more negatives.
The irony is that the Clinton Foundation has a lot more to answer for.
