I can't speak for everyone in the comments, but when I say the world's improving, it's a reaction to either defeatism ("we can fix the problem so you shouldn't stop trying") or calls for revolution ("don't flip the table over when things are getting better"). It's not that things are improving so we don't need to do anything else, it's that current efforts are working and we should keep going.
