If only I, as a single American citizen, could hold my tax responsibilities hostage from the government as well. You know, at least until they agree to lower my percentage to something I feel is more fair. If you are saying you wish the government would lower EVERYONE's tax rate to 15% so that the corporations would pay up, then sure, I'd go for that. But I can pretty much guarantee the corporations will continues to use their abundant resources to pay less than what they owe, no matter what the actual percentage is. Closing loopholes in the tax system is a bit like waiting for a bug-free software release. While I wouldn't mind the government putting a bit more effort into fixing the tax codes, I am not so naive to assume that they could ever come up with something loophole-free.
