Right - so this is actually a hard problem worth solving, unlike many of the problems that SV solves.

Let's acknowledge that and stop treating these people like Heroes because they got rich.

Wealth distribution is a hard problem, but it is a MASSIVE problem that most productivity gains flow to a subset of society.

Leaving aside disagreements by people(who a lot of them are politically motivated and maybe not the result of deep thinking and rational thought or aiming to benefit everyone), doesn't the research tells us about what interventions benefit everybody ?

For example, that socialized medicine is the better method to reach that goal ?

The difficulty with this is also convincing people that the research is valid and itself not politically motivated/without rational thought. As much as I would like research on what benefits societies in general (sociology?) to feed into how social policies are generated, I feel that there is also significant questioning on the validity of the research and how such research is conducted. Given that there are no real ways to fully account for all variables in the scope of this study, there may always be the argument that such research is shoddy and can't be replicated.

(I'm not actually arguing that such science is shoddy, only that the perception that they are shoddy and invalid is a strong disincentive to listen to any research on this matter. It's actually really disheartening to me that this is the case.)
