I don't think anyone can honestly say the UK hasn't gone backwards over the last decade or so. We can argue till the cows come home as to why, but fact remains it's becoming a really poor place to live and being up a family ( imo ). I may be biased as I'm fortune to travel a hell of a lot with work. But the one think I see in the UK that I don't tend to see anywhere else, in fact I see the complete opposite....is the fact that success in the UK seems to be frowned upon and actually discouraged. People see others success and don't say " well done, id like some of that and how do I get it" it seems to be "look at that ****er, how can I take that from them" or things to that effect. The welfare system here is completely broken and encourages the wrong type of behaviour from lazy people and the even mildly successful people have to prop it up. The NHS is completely ****ed from complete and utter incompetence and miss management and instead of actually fixing it, all political parties use it as a political weapon. Immigration isn't working at all and as with the NHS it's just used instead of being fixed.
More and more money is taken of workers in the UK, given to people who do nothing to earn it and into political pockets. Unfortunately though I don't think we're anywhere near the bottom yet either.
Our country has the potential to be absolutely outstanding yet again, but unfortunately I don't think there will ever be the desire from those in the political parties to make it great.
