I agree with much of what's been said already, but think the biggest problem is "
NO parent families".
The cost of living in this country is so bloody high that people often have to work their bollocks off just so they can buy, what are usually the most expensive cars, bikes, booze, fags, jeans food etc. compared with the rest of Europe and America, but most of all, very expensive houses.
Emigrating Brits may have put house prices up all around Europe, but your average couple outside UK can still get a house much cheaper than here. The average earnings are also probably dropping in UK compared with other places, especially if you take out the overpaid tossers who seem to earn an absolute fortune for doing nothing other than gambling our money on the Stock Exchange and still get a 911 for a monthly bonus

. (OK I'm jealous! But taking out this lot would be a good idea

).
Most couples haven't got a chance of paying the bloody mortgage, without both of them working, often needing more than one job each.
My daughter and her partner both do their day jobs and do other work at night to make ends meet, so they can pay for a modest house, they have recently bought. Even worse this year as they have decided to get married in August, and ended up sellin' the much loved CBR6 to pay for the honeymoon. (
So I'm back riding on my own now, it was really great doin it as a family thing).
Trouble is in most cases, both parents usually have to keep working when kids come along so kids are often home alone after school, or during hols, or looked after by grandparents, who struggle to come to terms with kids so different from what they were used to.
In places like Spain, Italy and probably France, the mothers are much more likely to be at home to look after the family, it may be thought sexist, but it used to work here for many years. They also got decent food when they came home, rather than the convenience food they get when parents finally get home from work now.
