The notion that audits should be evenly distributed is nonsense. Someone making sub-$200K usually has basic W2 income, versus someone making $20M a year who likely has an extremely complicated web of capital gains, deductions, strategies, carry-forward losses etc.
It doesn't even make sense from a pure cash point of view. It's better for an agent to audit someone making $20M and win a $500K judgement than it is for them to audit 1,000 $25K earners and fleece them $500 a piece. What a waste.
Audits should be exponentially lopsided, not targeted exclusively at the middle class.
Why bother commenting if you don't have any data to back up your assertion?
You can make claims about what "should" happen but that is just your fact-free opinion.
