Earlier quoted context omitted.
I agree with you about simplifying the tax code, but do not agree about reducing the tax-liability. Since these corporations benefit from society just like private individuals do, they should contribute to society (in the form of taxes) in kind.
Why not reduce the tax liability as well for people like you and me then? It would be one thing if governments could be trusted to spend the money wisely, but so far as I've seen (other than obvious exceptions such as emergency services and libraries) that's rarely the case.
I'm in favor of the tax-code placing an equal burden on everyone. I am against only corporations getting a free-pass though.
