The Treasury Department could monitor. Use the witholding method if you want, refund at the end of the year. Computers could crunch the numbers FAST. Penalty if you don't comply, jail time for problem cases.

John Kennedy drastically cut income tax and overall revenue from income tax went up. People comply with a fair system. Everyone knows you have to pay for certain conveniences.

A flat rate of say 10% on the upper and middle income brackets, tax breaks for the poor. Professional people would FLOOD to the U.S., too, to prosper under a fair tax system.

Progressive taxes have had their chance. They've failed. Too many thousands of pages of loopholes, armed SWAT teams collecting for the IRS, capital flight, etc. Scrap the old system.
