Well let's not pretend London is a city that runs on an economically - can't think of the word - rational(?) basis. The economics of London stopped making sense some time ago.
I don't disagree. Have I said I support the status quo? You appear almost to be having an argument with yourself: tagging my posts but then responding to things I have not said or even insinuated. 
But as a city it requires underpaid serfs that increasingly can't even afford housing, so if it wants to tackle its issues, it needs to consider everyone.
"It" is a city, it doesn't consider anybody. Again, I will reiterate that in order to have a sensible discussion about the structural issues in the UK economy and feasible policy options to change it, it is vital to discuss facts not conjectures or assign viewpoints or opinions to others that they have not given any indication of holding. Policy making needs to be evidence-based to be effective.
And that means that if you want change you have to engage with the facts as they stand and have an accurate picture of where we are and why, where we want to be (and build consensus on that, with evidence regarding why it will be better) and then - again using evidence - determine the steps to move from the former to the latter.
That may seem boring to you and if you prefer to be hyperbolic and try to start arguments with people for no reason and make false assertions that don't match the facts of reality then we will get nowhere with anything in the UK improving. Slogans and rage are no substitute for rational thought.
