>How/why do you not promote the growth of denser, middle class inner city neighborhoods with a diverse profile? Is there a positive reason to not encourage it? More houses = more taxes. Development is promoted in less dense areas because it creates jobs and brings in money. New constructions are profitable, and the industry is basically dictated by builders that throw up cheap houses on plots of land they bought for 10k.
