Besides the pretty obvious fact that my husband and I pay more taxes each quarter than Trump has paid in 16 years, the glaringly clear takeaway is that if Trump isn't paying taxes, someone else is. Of course since Trump's total tax payment to the US Treasury for two years was only $1500 it isn't even that hard to pay more taxes than Trump. The average American pays more than $12K per year and even many people on Social Security pay more than Trump. While there have been several people who blame the lax tax laws, especially those around "development", a fair amount of what was reported in the NYT isn't legal, with the previously undisclosed consulting fees paid to Ivanka as a case in point. That doesn't make Trump a smart businessman and it certainly doesn't make Trump a successful businessman. If you make excuses for Trump's behavior, you should probably examine your own ethics and morals.
If Trump is innocent of wrong-doing, he can reveal his taxes. I don't recommend holding your breath while you wait for them though.
