Well, if everyone were like me, then everyone would be hard(ish) working and honest. There would be no more thieves, or public assistance hustlers, or people who rip off old ladies.
If everyone were like me, there would be a lot of deliberation before things were done. There would be less stupid impulsive decisions. That would probably lead to less divorces, less affairs, less abortions, less of all kinds of things we could do with less of.
If everyone were like me, animal abuse would pretty much stop. People might get mad and THINK about killing the cat, or even TALK about killing the cat, but that would be OK, because it wouldn't actually happen.
If everyone were like me, we would have less trouble with excessive consumption and environmental degradation.
If everyone were like me, there would be no perfect parents, but there would also be no parents who didn't give enough of a damn to try really, really hard to do right by their kids.
If everyone were like me, there would be no different ideas. There wouldn't be a whole lot of innovation, because I like things the way they are. There wouldn't be much music, because I like music, but suck at making it. There wouldn't be a whole lot of socializing, and socializing is good, if not for me, at least for society in general.
People should disagree. They should think and feel differently and learn to work stuff out. Life would be really dull if everyone were like me (or anyone).
