Or perhaps you are drowning in debt and hoping for an easier way out?
I've heard conservative estimates for a national sales tax, and they have all been 20% or more. I'd assume it would rise closer to 35 or 40%, as politicians always underestimate the real costs of everything.
Not to mention that it would encourage businesses and certain individuals to simply buy overseas, causing greater loss of American jobs. It is a tax on consumption, which clearly drives our economy.
And the wealthy get off, as they will spend a much smaller percentage of their income on taxes via their tendency to stock their money.
