So, we'll pay another 3 cents on the dollar for the commerce we have with the big corps. If it bothers you that much, find non-corporate people to do business with. What we're talking about here is, for instance, if your net income, after taxes, is $350,000 for the year, your income will be $347,000 without the tax cuts. I do not find much sympathy for you, whether you're a corporation or an individual.
(Here's where all the business "experts" will jump in and correct me, ignoring the words "net income" and try to obscure the truth with tall tales about local taxes and obscure business expenses. Go for it.)
