Carbon taxes aren’t merely pointless, they’re regressive. Politicians earn ‘green’ cred by making life worse for the poor.
When Canadian drivers fill up our gas tanks, 35% of the price we now pay is tax. If the average tank holds 64 litres, every time we gas up at $1 a litre, we’re handing over $22 not to the producers and distributors of this product, but to the government (see p. 4 here).
Since poor people have less money overall, taking $22 from them at the pump is a big deal. Via gasoline taxes, the poor are forced to pay a higher share of their income just to do ordinary things such as get to work, drop their kids at daycare, fetch groceries, and visit ailing relatives. This is called regressive taxation.
