Social contract is broken?

I’ve just returned from a trip to New Zealand and the difference in attitude is stark. The streets are clean, people are friendly and happy/helpful and in general people seem to want to participate in society. Don’t get me wrong NZ has a lot of issues but It feels like in London the social contract is broken. Streets are full of trash, no one gives a shit about anything, phone theft, crime is high and in general people seem fairly miserable. I was involved in an accident where I had to give a victim CPR and the ambulance and police all arrived within about 5 minutes. I was amazed at the emergency response. It feels to me like the state has given up and hence people have given up.
