Profits don't generally have a simple/strict meaning in business terms, AFAIK. Maybe you mean EBITDA? (earnings before interest, taxes, depreciation and amortization) I think even that is maybe not what you mean/wouldn't acheive your goals, even if it's theoretically unambiguous, because of what is invested in R&D/aquisitions/etc.

Also, presumably you're talking about new laws in the US here? What stops businesses from just moving their HQ overseas to places with different laws they like better?
