$500 billion is a sizable chunk of that $6.3 trillion, and it's still only a 25% tax rate, and then only the "ultra-rich."

If one considers something more reasonable, like a 70% tax of income over $100,000, then you're talking about more substantial amounts to really start catching up to top economies.

I wasn't saying favourability ratings should be used to predict elections. For that you have polls (in which Trump has a substantial but not decisive lead). I was just responding to the comment about who is more unpopular.

I think that people who respond to pollsters overwhelmingly know that Trump was president before, and clearly it doesn't bother them what a train wreck that presidency was. It's not clear to me how they would suddenly start realizing that closer to election day.

Actually, we're not a long way off from that. Hydrogen production facilities utilizing (excess) renewable electricity output are under construction as we speak. For example, a large project in Kazakhstan (which has large stretches of windy, sunny and empty steppes) is aiming to be online in 2030 with 30 GW of production going towards green hydrogen.
