I've come up with a stupid idea. The government could commission the creation of a new town, a bit like Milton Keynes.
But this time it would just be one massive skyscraper. Inside the skyscraper would be every facility - a post office, primary school, high school, college, university, offices, supermarkets, shops, hairdressers, a hospital, GPs.
It would be a bit like having a space station but on Earth.
