Why are there so many ignorant, uncaring people in this world?

Every time I get on the internet, or venture out into the world, it seems like human beings in general are very inconsiderate and/or ignorant. Sorry to be so cynical but sometimes it just seems like society is getting worse and worse by the day. Whether it's some maniac who cuts people off on the highway, a child who has no respect for his parents, or even someone on Yahoo Answers/YouTube who doesn't have the decency to write a cohesive statement or better yet, responds with an unintelligent argument, it all seems like it's going downhill. Are there any other people out there who feel similar or is it just me? And will people ever get better? I blame the parents lol.
