I'm in favor of eliminating the income tax entirely and moving more to a sales tax-driven system for bringing in revenue.
Yes. I think this would be the logical next step, but I don't see any large things happening all at once. Most countries just aren't geared for it. It needs to be incremental change and once started, it can start to speed up. Unfortunately, we are going in the wrong direction - and it is speeding up the wrong way.
