Since you are a lawyer, I doubt you could accept common sense answers. The easiest idea to dispel with is the notion that anyone pays a tax other than the person who produces the wealth. If you can grasp that concept then you may be open to the idea that tax lawyers are not indispensable.
Your hard on for lawyers aside, I think I see what you are saying and agree with it. That’s why I think the corporate income tax ought to be eliminated - corporations should be “pass through” just like partnerships and most LLCs. There is no reason for the double taxation of income just because it is earned in the corporate form, other than rank populism.
