This has been my theory, but it'll take longer than 50-100 years. It should coincide with Earth's population decline. After technology removes another 10-15% of jobs, and we settle into global warming, the population should settle at ~3-4 billion, with ~80% of it being service and maintenance workers, and the rest as the controlling elite.
