AL, it is obvious that YOU have never run a business. Your claim that the impact is at the margins, but fail to account for the margin (ie profit margin) in the first place. If a product is currently providing say a 17% profit margin and that possibility that taxes may rise and regulations instituted that take that to a 5% margin, are you honestly going to tell me that this "impact" will be only secondary or tertiary to how that business is run? If so, you are sorely mistaken. I, as a business owner will have to decide whether to take the money I was going to employ in this business to possibly earn a 5% margin, or park it in an investment that earns 3.5% (for sure). This is NOT a secondary impact, son.
