This is absolutely true about the IRS. In general, the poor and middle class have their money taken from them, and have to prove every credit and deduction to get it back. The rich simply claim what they want, and hope they don’t get an audit.
Also, I get the impression that if the poor and middle class are found to have made a mistake, then taxes and penalties get layered on top causing additional pain.
But I believe that on more than one occasion, the Clinton Foundation had a tax filing problem where they failed to pay millions, and they simply re-filed. No big deal.
