I tend to believe that rich politicians aren't going to vote to raise taxes on themselves - they're going to instead gut the middle class (hence the trends you see today.)
>Despite a $2.7 billion transfer to the state treasury, the Alaska Permanent Fund earned enough from its investments to grow by $1.4 billion, or 2%, during the just-ended state fiscal year. As of June 30, the fund stood at $66.3 billion, up from $64.9 billion on the same date in 2018.

You know how rich people only have to exercise very mild discretion with their spending because of how much money their money makes? A social wealth fund is sort of like that but for everyone. I think those dividends will be lasting quite a long time.
The writing is on the wall, all PFD earnings will go to run state government in the very near future.
What is that?
Plenty of countries do this (even Alaska) it's easy, it's understandable, and it doesn't store away the money.
