Indeed, what are we waiting for?
Nobody in the world can possibly understand or fully comply with our current federal tax code, which weighs in at a whopping 10 million words. Even tax experts — lawyers, accountants, legislators, etc. — don’t agree on how to interpret the tax code monstrosity.
Oh, and to answer the question as to why a flat tax or the FairTax hasn’t been adopted — it’s because the legislators who would have to draft and pass the new law are the very people who benefit most from the burdensome and easily corrupted system they’ve built to fee their own greed and pride.
Why don’t we have a more simple and equitable tax system?
Because of morally bankrupt law makers.
The love of money really is the root of all kinds of evil.
