It's certainly a strange phenomenon and one that sadly seems to be only prevalent in the UK. It seems in this country you aren't allowed to enjoy your success without someone getting upset or jealous. Totally the opposite to most of Europe and the US where people are on the whole, positively encouraging.
We seem to have created a culture which rather than encouraging and applauding people to strive for better, seems intent on beating everyone down to the lowest common denominator. Most of the world seems to have given up on Communism but it seems it's very much alive and well, right here in the UK!
