I'll miss his 9 9 9 plan.
Plans for the federal government should not be based on a catchy ring in a TV ad.
There are benefits to simplicity, and we should strive for a more simple tax. But, one-size does not fit all. One-sized plans will do immense harm to America. We need simplicity, but not all the way down to one-size for all. Heck Cain himself adjusted it to 9-0-9 whenever he was talking to a specific group. Just make it 0% tax for whomever you are talking to!

My main beef though, is if you went to a X-Y-Z plan, the chances are zero that the best plan for America happens to have the same numbers for X, Y, and Z. There is an optimum (most economic growth, least debt, most opportunity, most fairness, etc), but, a catchy 9-9-9 ain't it.
In the end, to me, it will now be a 9-9-9-Covid-19 plan.
