This would eventually result in violent revolution. Suppressing that revolution will require a complete forfeit of civil liberties. There's another reason it's bad too, and it's economic: in this world you will not be able to get ahead. These super-concentrated mega-cities will see runaway real estate inflation due to the "law of rent," while jobs will be scarce elsewhere. The choice will be: move to a "real" city and spend all of your surplus income on rent, or live elsewhere and have no opportunity to advance your career. The urban model looks a lot like the old "company store" model, which is a form of feudalism more or less. In the end this future looks like a 1980s B-grade cyberpunk dystopia: endless slums and rural wastelands patrolled by drones and special forces officers and dotted by gated totalitarian enclaves for the super-rich. "DNA sample and body scan are required for entry..." You said "liberal." What is liberal about this?
