That's a good point. I was more thinking in response to the conventional idea that there is a 'race to the bottom' when it comes to corporate taxes - which rests on the idea that a corporation operating in a given country is inherently good, no matter whether they pay taxes or not. In general, though, I would argue simply that regardless of the specific tax revenue figures, if a company doesn't pay taxes, they get free access to a lot of services other people have to pay for. That is in essence a subsidy. There's no compelling reason why the public should subsidize a private concern. This goes double for a competitive marketplace, where companies that aren't subsidized in this way will suffer (and have suffered - try competing with amazon on price while paying taxes!)
