I think, over the last thirty or forty years, there have been some negative changes to society ( and yes, of course some positive ones as well).
Children have a lot less freedom nowadays, and seem to be left to their own devices a lot less.
The internet and social media have become ubiquitous and many people seem to live a large portion of their lives through Facebook etc. Likewise, many people seem to be more interested in texting and tweeting than engaging with the people actually in front of them.
There is more pressure to have 'stuff', it's much more difficult to buy a house, and a lot of families are forced into being dual income households regardless of whether one parent would prefer to be at home with the children.
People spend far more time commuting, and work longer hours than a generation ago.
As a result of a lot of the above, there has been a gradual erosion of community spirit and solidarity and increasing numbers of people do not know their neighbours, or live near family and friends.
No, I wouldn't like to return to the Victorian era and be a scullery maid living in a basement bedroom and having to be up at 5 to light the fires, but I do think it would be nice if we could row back in some ways.
