Ignorance is bliss, and how do you know if the grass is greener on the other side if you've never seen the other side? Unfortunately we are plagued now with easy access to information. As much as this can help society, it can also destroy it. Disease, war and a lack of food may plague some third world countries but it is the first world countries that have the highest suicide rates.
We have more choices and freedom than ever now. Where as before you were pretty much stuck with what you were born with. Some people can't handle the current competitive world, full of info that society pushes on you in order to keep up. Even reading was highly unnecessary for most a century ago. Now everyone thinks they're an 'expert' because they read something on the internet. I don't think today's society is any worse or better really, it has just changed. Instead of struggling with survival now, we are struggling with a REASON to survive... which seems to lead to a lot of depression and whining.
Depends on what time scale. From Ancient Rome, or ? Its gone to sh*t. From the Victorian age? F***yeah. I'd say right now its confused. Parts of it aren't as good as society in 1965-1980 but parts of it are a lot better. I'd say its a lot better than it was 1600-1965. A lot better.
