I wasn't crazy about adding a new tax, but after looking at it, it's not so bad:
1. It encourages saving. The combination of incentives to invest and incentives to save will ignite the economy and it will boom.
2. Many Libertarians, who would prefer no taxes, say the Fair/Sales tax is the best if we are going to have taxes.
3. Along with the sales tax, we would, under Cain's plan, get:
The current tax code would be thrown out completely.
No other viable candidate (except Ron Paul, who might not be viable) is going to lower taxes and change the system that dramatically. .
Surely nobody thinks that the 999 plan in its current form is going to be the one that is finally implemented after the years of hashing it over have occurred. Who knows what it will be by then?
