If the IRS went away tomorrow, we would find other things to do. I support reforming our system. We don't actually see the money. If we had to write a check every month for our tax bill, people would really care. If you add up income tax, sales tax, property tax, etc., etc.
Many professional organizations lobby against reform.
This is silly. We will always need accounting for business even if we go to a national sales tax or a flat tax. I heard that we work until June 26th now to pay all of our taxes, such as gasoline, phone tax fees, sales taxes, etc. We work about half a year to pay taxes. We fought and won World War II with a lower tax rate than we have today.
