Would you disagree with the claim that several significant social problems have in fact been solved over the history of human civilization, at least in parts of the world? Or are you saying that those were the low-hanging fruit and the social problems that remain are nearly impossible to solve?
What would you say about the progress that has been made towards satisfying the Millennium Development Goals?
Looking at the list, I would say that to the extent progress has been made towards them (and to the extent they're worthy goals, the "sustainable development" one is trying to solve the wrong problem and the "gender equality" one is just incoherent) it is incidental to the efforts of the UN.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
