The IRS is understaffed.
The 12 million documents exposing illegal tax avoidance by the ultra-wealthy, called the Pandora Papers, succeeding the Panama Papers, shows that some significant portion of the very wealthy avoid taxes by illegally concealing billions in assets and income generated by these assets. The vastly wealthy understand understaffing the IRS is their best insurance against being discovered as tax cheats.
It is in the interest of ultra wealthy tax cheats that the middle class should be upset with the IRS. Understaffing the IRS achieves this.
It is basic to our progressive tax system that those with incomes in the top 10% fund our government through higher tax rates than the middle class. Unfortunately, some significant portion of the very wealthy shirk this obligation illegally, year after year. The IRS could provide better service and our federal and state budget deficits would be significantly less, if the IRS was better staffed on a multi-year basis.
