Zoning laws are mostly to blame for lack of affordable housing. That, and the usage of houses as an investment. When you spruce up a house, that attracts different renters. The other renters will take up housing otherwise they wouldn't have bothered with, and it goes on down the ladder. The argument that market rate housing causes lack of affordable housing is just not true. Look at San Francisco. They have strict zoning laws, laws against construction of market rate housing, and rent control laws. Is it a paradise for low-income renters?
