I think it’s a fairly balanced article. In fact, most of it is devoted to spelling out the positives in Cain’s plan.
The problem they see, though, is that there is nothing to prevent the tax rates from rising, and there’s nothing to prevent the acceptance of the sales tax part without ever lowering the income tax rate.
Better, I think, to have one new amendment that simultaneously (1) repeals the 16h amendment, (2) prohibits anyone from instituting a legislatively authorized income tax, and (3) institutes a national sales tax with an upper limit of X%.
If it isn’t nailed down by the constitution then the legislature can easily keep raising the rates. They always have in the past. They’ll try again.
I read your comments as really going to the process — the best way to implement and embed permanently the plan.
That’s a very good discussion to have. But some people seem to confuse “if the process seems hard or murky right now” then “the plan is idiotic.”
