We have an infinite money printing machine. We don't need access to any capital. That's not what the carbon tax is about. We need to change behavior. We need everyone that uses carbon to pay for its use (including the externalities) so that they stop using it as much as they are. This is why poor people can't be exempt. This is why the rich can't just pay for it. We all need a massive increase in the cost of everything that touches carbon (read everything) so we start driving to the next city once per year instead of every weekend, so that we start eating a BLT once a month instead of twice a week (a lot of heart issues down here in the south for a reason), and the list goes on.
