So I thought the consensus among economists, hn, etc was that the best most painless way to solve climate crisis is a carbon tax, that doesn't drastically alter the economy all at once. So what to do with the tax money? Presumably invest in green energy. A lot of that can help people directly, like solar and nuclear jobs, and indirectly, like better trains, or subsidies for the poor on any essential goods that price was raised by the carbon tax a lot. We can probably find a use for all the money raised by placing a carbon tax at the rate needed to prevent catastrophic climate change. But if we put the tax at the right rate and have some money afterwards, what's wrong with free college?
