Yeah, but you know what they say about giving someone something and then trying to take it away. The first three would work great for the upper echelon but, as you imply, not so well for anyone else. Imagine the lobbying then to keep the new normal.
Of course, if businesses don't wish to pay corporate income tax then they shouldn't be corporations. If it means that much to them, then they can reorganize their legal structure and deal with the varied consequences of their choice.
And, as most would agree, a consumption tax would be crippling for the lower echelons, but no doubt the rich could live with that and several influential of their number would seek to maintain the new status quo.
I know you mean well, nitro, but you give a Rightster an inch and, well, you know the rest.
