Leaving aside any argument of social conscious or just 'doing the right thing' do you really want to live amongst PLUs? (People like us). Firstly our society will be all the poorer as such annexing is well proven to exacerbate a city's social problems.
However, back to you. Continue to artificially manage society in that vein, you will find yourself in only a few short years not to be the gentleman but the pauper that owns a house that really should take his money move on as he's not the sort of person we want around here. Nice.
I love all the development and investment - let's have more of it, bring on the bakers, coffee grinders and green grocers with their over priced organic goods, I'll buy it all. But such development should not come at the cost of key public services and a choice to have a gammon and chips with a pint for a fiver at the Capitol if that's what I fancy.
