And it needs to end, now. To quote the left, “Never waste a crisis.”, so use this to end the IRS and adopt the FairTax or something else.
My suggestion:
1) abolish the IRS. Fire ** EVERY*** IRS employee.
2) The federal government sends a tax bill to each state governor ( size of bill based on latest census.)
3) The states figure out how to collect to pay for it.
With 50 states, eventually, the least intrusive and least economically damaging method of collecting the taxes needed to fund the federal government will emerge.
