I'd argue that despite this article and other stories like this one, modern society is less screwed up than it has been in the past.
Modern Society is screwed up just as much as it always has been - and in pretty much the same ways. There are very few new ways for us to invent (and the old ways are still the most popular).
What has changed is that the world population has increased.
1% of the population being completely off their chump isn't many when the population is only about 1 million.
That's one idiot per village or one black sheep per family.
But when the population is 100 million you start getting whole communities of them.
You also have to bear in mind that being 'screwed up' isn't the same as being socially inept or being not very bright.
Most of what is perceived as being signs of the decline of Society is just people being dumb or unable to cope with life or both.
Someone who hasn't got that many brain cells is easily seduced by a virtual world in a computer. There life is more basic and uncomplicated with few of the unpleasant consequences found in real life - a bit like TV soaps.
Small wonder that people often get confused between what is real and what isn't.
You see it happening here on a regular basis.
The only hope for mankind is that all the wing-nuts will stay plugged in to their computers leaving us intelligent smug b*stards to get on with running the world.
Which is why I'm starting a campaign to give all politicians a computer for Christmas.
