Yet living standards aren't improving an inch.
Housing price to income ratios are higher than at any time on record.
Outside the city, populations are decaying year after year, and the only chances of benefiting from global economic trends are in the city.
There's a housing bubble in virtually every major city of Europe due to speculation and migration from smaller towns.
To put an example, in London median house price hovers around half a million, while median London salary is about 30k. Sure, your washing machine is cheaper than 40 years ago, but the basic element in any economy -housing- has become more expensive. Cities are saturated in every sense.
Except maybe the idea The Economist wants to push is somehow that we need millions and millions more ex-EU immigrants? Because they have seen a spike in underpaid IT vacancies.
