I believe Thomas is for an overhaul. I believe he supports a flat tax (sales, not value added), limited Corp tax, no inheritance tax, etc.
Pretty mainstream...
One of the biggest problems with the Fed Gov is their Bookkkeeping is not GAAP. They have too many things "off the books", like unfunded liabilities. It misstates the debt and does not provide adequate info for proper decision making (as if that is a desire).
Another idea....the Speaker of the Hosue does not have to be a sitting Congresscritter.....they should elect Dick Armey
Thomas does not support a flat sales tax. Furthermore, a sales tax is a kind of value added tax.
