Yeah... the world just seems to be getting worse and worse. Not sure if you meant the world in general, or just your situation, but... definitely the world. Everyone who has the actual power to change anything aren't doing anything to change, and the people who want change have no power to actually change anything.
And, yeah, as pointless as it is to want to change the past, I wouldn't mind doing it if I could. Still, that isn't even taking into account the butterfly effect... ugh, time travel is confusing.
