The Carbon tax definitely caused raised prices on goods. It’s not the only cause, but it’s there.
Corporations are not in the business of losing money, so when it costs them more to bring their goods to market that cost increase is passed on to consumers. Our politicians don’t care that people’s purchasing power is going down the drain, as long as they can virtue signal about the environment.
A carbon tax doesn’t affect the wealthy as much as regular folks. When you make millions, you’re never going to change your driving habits because of the price of gas.
