Carbon tax takes a cut from ultra-wealthy corporations and passes down to mass consumers, with some kickbacks to green initiatives along the way. There's no other way to cut that.
To say that corporations "need" to pass the costs to us is to completely ignore multi-billion dollar record profits, and assume that each CEO is "entitled" to 2,000x the wages of each employee, because it's only right. You're just being a corporate shill, there's no other way to cut that.
