Stackoverflow and the associated sites are more or less like that. It sometimes has problems with overzealous users marking tangentially related questions as duplicates but overall it seems to work.
Downvoting costs karma and it’s encouraged to give reasons for a downvote. If an answer is outdated a newer answer often quickly rises to the top and often enough the original answerer will promote the better answer. And you can also edit other people’s answers and you can see an edit history.
But it only works if there are enough knowledgeable people participating. It’s especially bad with new questions because either the question is low quality or the first answer which gets accepted by the questioner right away is bullshit.
Because it’s one of the few true ones? The media and politicians trump up fears of immigrants and poor people while downplaying or ignoring tax evasion, both legal and illegal.
OP’s solution would be getting rid of capital all together and becoming best buds with China and Russia, as shown by other posts. But that is not expressed here.
Ironically, becoming best buds with Russia is something the Left and the Right agree on. At least in Germany.
Strange. A weird “fact” I heard in my childhood was that the yolk contained more protein (also called eggwhite in German) than the egg white. Meh, too tired to research it.
