Philip Truscott examines the Singapore model:
Jane Jacobs famously complained that the public housing projects took some mixed income neighborhoods which could have been viable and sealed their doom by concentrating too many low income and unemployed people in the same buildings. Singapore’s HDB does act as a direct landlord for a very small number of people who meet a strict income ceiling (about $1160 USD a month), however the low income tenants are spread thinly among owner occupiers. Income ghettoization is limited. My realtor tells me that one of the blocks in my own HDB estate is for tenants rather than owners but from the outside I cannot tell which building it is. Another form of deliberate social mixing takes the form of racial quotas intended to prevent the formation of ethnic enclaves. Access to the more attractive and less attractive neighborhoods is shared out more equally.
