Too cheap for who?

There are carbon taxes being implemented and on the whole i think they are good. But combined with the current spike in energy prices, they are hammering some people.

Give the poor money, if you care about them. That's more efficient than making the tax system more complicated.

Too cheap for the climate, i.e. too cheap for anybody under 40. A tax-and-rebate system can help poor people without hampering the effect of a high carbon price.
