The HN crowd might over-allocate $1000s per person to NSF, NIH and NASA and short Social Security while 100+M people contribute $0 to science, but depend on SS to survive. We might end up with the same budget but people feeling more in control.
We'd also see large scale advertising which is actually a good thing: ads are pretty cheap/efficient, make people feel better about their government and society, and employ an army of creative people. I imagine you wouldn't see branches of government running negative ads against each other - it would be more like the feel-good military recruiting ads today.
Sorry if this sounds utopian, I've had a rough week (in addition to everybody's rough week) and need something to feel good about.
