I am as libertarian as can be, once one is aware of existential risk.
I prefer a basic income guarantee to a paternalistic regulatory state. I like the NIT for its simplicity, but am opposed to high income taxes. I prefer the georgist land tax. I believe that if the land were taxed well enough, people could not just hold it and make living expensive for other people. Almost everyone would have the option of going a distance and setting up something of their own over there.
That is the taking. Now the spending.
I believe that we should aim towards a meritocracy.
So, most importantly, a strong minimal state providing justice, protection, primary and secondary education should be present. If you're hitting marginal contribution of zero over there and still have money left, move to the next item that can help.
Basic research into intelligence and conscientiousness augmentation. Aim to make IQ85s into IQ 110s if possible. If, as a side effect, you can boost some already existing people to higher levels, that's lovely, but that is not the goal. The goal is to turn 80s and 85s into 110s and 115s.
Basic research into happiness augmentation without affecting effectiveness. Aim to increase happiness set points across the board.
If you're hitting marginal returns and still have money left, then try to institute a prize that will be given to firms that employ a large number of workers. The product of wages of the workers is a good proxy to try to aim towards. (This is actually quite hackable, but if done well, it does have the advantage of multiplying the prize amount, using dollar auction effects)
After all these, if you still have money left, one can try the NIT or Morgan Warstler's variant
That is the taking. Now the spending.
The georgist program is about people compensating others when they presume to control part of a commons. Maybe it is a preferable tax system to taxing labor, but removing the compensation part of the program vitiates the original point.
The last thread didn't fare too badly, I think; let's make it a monthly tradition. (Me, I'm more interested in thinking about real-world policies or philosophies, actual and possible, rather than AI design or physics, and I suspect that many fine, non-mind-killed folks reading LW also are - but might be ashamed to admit it!)
Quoth OrphanWilde:
Let's try to stick to those rules - and maybe make some more if sorely needed.
Oh, and I think that the "Personal is Political" stuff like gender relations, etc also belongs here.
