As I mentioned before, I can partly agree with your comments, but really it's up to you where you live in the UK.
There are still many great places....likewise there are certainly many parts of Thailand that aren't so good. Be it racism, poverty, boring area, too hot for some etc.
Noting your comments about the UK, well to compare...living in Thailand, you have to pay annually immigration and that may increase, a overpriced cost to buy European style food products, corrupt police, worlds most dangerous roads etc etc
Sorry but I think more people should look at the positives of the UK and Thailand and stop thinking about how it was!
Thailand for many is great and so is the UK for some.
