FairTax is regressive and does nothing to stop a trillionaire from launching dick rockets to nowhere. Each rocket and launch using more resources than a poor person will their entire life.
So you oppose green tax policy on the grounds that it isn't punitive enough against rich people? A rich person living a miserly life would pay little in taxes, I see no problem with that.
I assume that you are alluding to someone specific with the rocket launching trillionaire quip. That would be the same person who helped make electric vehicles viable and also helped develop reusable rockets, far greener than one time use ones, no?
Though, I do recognise that having one regressive tax wouldn't necessarily make the entire tax-and-transfers system regressive (or even more regressive, if that tax money is spent).
