I don't think it's being ungrateful, or at least not something unique to Londoners. People think and act relatively. We will always complain about the biggest issue we face, not matter how trivial it is compared others. Or you could say, we always try to improve no matter how good things are. We shouldn't stop fixing things or improving just because someone has it worse.
