You're missing the point. It would deeply widen the already large gap between the upper and lower classes. And the worst part: it still wouldn't fix the problem

You're missing the point. It would deeply widen the already large gap between the upper and lower classes. And the worst part: it still wouldn't fix the problem. The really carbon expensive aspects of society come from industrialization. Fossil fuels are not "optional". Without them none of the global supply chains would function. VERY few would have electricity in their homes. Building infrastructure would be insanely expensive to build with a carbon tax.
