I have no problem to pay flat tax. How about everybody in the entire country pays flat tax, with certain deductible for each head to protect the poor?
Besides one universal deductible for every head, there is no credit or deductible whatsoever. No special interest for any industry. No more tax law lobby activities.
Tax law would be a lot easier. It will save everybody enormous time to file tax. IRS can save 90% of their man power.
