What is just temporary
Be wary of those asking for a VAT or flat tax. Politicians will offer that they be temporary or very small, “not even noticable,” and then they will ratchet it up.
BTW, they will promise to phase out the income tax as the flat tax ramps up. However, I betcha that we will end up with both. Some form of income tax AND a flat tax. Sort of a two for one deal.
