I think a lot of us are also missing a pretty key point. 

Trump likely didn't pay taxes, because we have a system so skewed towards the rich, that he legally didn't have to pay taxes. To be honest, I can't blame him for that (assuming he was legal on this, which seems quite likely). 

Again, I'm no Trump supporter, but if you are outraged at Trump about this, I suggest you are focusing this particular bit of rage on the wrong con artist(s). 

We might do better to look at the system that allowed Trump to avoid paying taxes, how system came to be, and who the key players were/are that created it and continue to support it.

Personally, I think we've been getting ripped-off and lied to from all sides for quite some time. This likely to be our downfall.
