The problem with that is that either a) you go under the margins and each sale is a loss, meaning that the company will offer no services at all; b) you stay under the margins, but not enough for the investors to keep investing (they expect higher profits elsewhere) and so the company now has no investors; c) you cut into the margin so much that it is not worth it for the company to continue developing new stuff.
In the case of c they will most likely continue to develop new stuff, based on their revenues elsewhere, but at that point the high tax areas are leaching of other low tax areas where the company can afford to fund innovation.
That assumes that you can find out when a company increase prices based on higher taxes, as opposed to anything else, which you cannot do.
The only real solution is to tell the retirees that they are not getting the money they counted on; that is hardly unfair as I am sure nobody here expects there to be any retirement funds for them, except what they can save up.
