Better People?

I was going to respond to a blog that Brandon posted where he asked this question:
"do the bad things that happen seem more terrible as some of us become better people then we were in the past?" But thought it warranted a separate blog.
I've heard it mentioned in class a few times, that we are becoming better people...My question is just that - is this societies people better than in the past? Are our politicians (Clinton/Foley) better than or worse than Brutus in Julius Caesar's time?
Also, what exactly are we evolving to? What is the measuring stick to show that we have arrived at our evolutionary goal?
