My gas and electric bills are often in the $300-$500 range. Until I have alternatives, taxes will do nothing but make my bills bigger and suck more money out of the consumer economy.
The bigger picture is about global competitiveness. The federal debt plus unfunded obligations is already something like $650,000 per person. The only way we can afford that is if our economy has massive growth, and any extra tax burden on businesses, whether for health care, the environment, or any other cause, is going to reduce business growth and drive jobs and entire businesses over seas. We already have some of the highest business taxes in the world, and massive levels of debt compared to GDP so if the question is could we afford to pay 10% more, the answer is a definite no over the long term.
