My sister is an IRS agent. She serves her country and her president, and it doesn't matter what party that president belongs to. She often gets disgruntled people saying they will write their congressman. Her response is "That is appropriate, congress makes the law." I might add that that she never gets outrage from middle class people, it is always from those making well over $250,000 a year. And it is usually because one of their many deductions is not allowed.
IRS agents do not go our and collect taxes. Law abiding Americans file and pay their taxes. Guess you aren't old enough to actually file and pay taxes.
