I think the solution is to add a stipulation to the sales tax portion of his plan. The sales tax won't go into effect until a constitutional amendment passes that:
If the amendment is never ratified, then the sales tax part would never take affect, and the plan would just be a standard flat tax (your suggested 9-9-0 plan).
I happen to like a national sales tax, but I understand people's trepidation about it. This would seem to be an answer that would address their fears, and allow us to go forward with overhauling the tax code.
Given the countries moode, the 2/3 requirement to raise taxes would probably be a big vote getter by itself (imho).
Cain has said his current plan is a starting point, not the end product, so there's no reason it can't be modified to address voter's concerns.
I’m curious if there is any thought given to only taxing durable goods and not food. I think more people would support the sales tax if it didn’t include food. That’s how it’s done in my locality with our local sales taxes. An increase of 9cents on the dollar would probably not sit well in bigger cities where local & state sales tax is already over 8%. I understand how with the other taxes eliminated it would actually transfer to a SAVINGS, but I’m curious as to how we can push this plan with people who are already being taxed mercilessly on a variety of things they purchase already (take gasoline for instance).
Please do feel free to direct me to a website, or the like - I know I need to increase my understanding of this plan.
