The least painful way to reduce population is through falling birth rates. In some places the birth rate is below the replacement rate. Those places also usually have excellent public transit.
Good public transit makes urban living more comfortable. When people urbanize, they find out that education is more important than having more farm hands. They also find that raising children is very expensive. Birth rates fall.
