It may be inefficient, but I don't think it's hopeless. And these are not people who lack compassion, and while they probably have some investments, the bulk of their income comes from their salaries.
I've been thinking a lot about what the purpose of ETPedia after getting slapped around by ThatBritGuy in an earlier discussion on that topic.
In addition to being a position-paper container/ideological framer/attention attractor, I think what ETPedia can do -- through position papers and/or through more modest articles -- is present arguments on issues that are specifically designed to address and defeat oft-used counter-arguments, and to do so in an utterly non-contentious manner that presumes the reader is in good faith and open to considering the arguments on its merits.

Another argument derives from Aristotle's Ethics. He asked how any thinking person could be happy. No matter your current state of affairs and reasons for felicity, you must always be aware that all could change tomorrow. You could be struck mute and paralyzed. See your fortune lost to theft or opportunistic legal actions, see your sons killed and your wife and daughters raped and be powerless to prevent or avenge these events. Knowing this, how can anyone truly be happy? My father used to say: "Only fools are happy."
Think this surely can no longer be the case? Consider the latter years of Joe Kennedy. Consider John Ramsey, his wife Patsy and their daughter, Jon Benet. The only possible defense against such calamities is a strong and caring community and a just society. We are far from it. Your friends can deny that this will happen to them and may well be right, but perhaps these considerations will at least disturb their sleep.
