Tech is not the sole cause of the housing crisis in San Francisco, according to CityLab staffer Kriston Capps, who asserts that other factors are at play including a lack of housing caused by wealthier homeowners. Capps examines the issue through the lens of a response to a New York Times story on the housing shortage from Gawker’s Hamilton Nolan, who wrote what Capps calls a wake-up call for San Francisco.
Capps points out that Nolan's assertion that new things can be built "in other places" is part of the problem:
Since the residents of high-cost, high-demand neighborhoods tend to have mobility, money, and access to information and power, they are hugely successful in leveraging land-use policies to exclude newcomers. They protect what is theirs and shut the gate behind them. (Nolan gets that.) So the high-margin development that really should go into the high-end neighborhood winds up replacing cheaper, older, and abandoned housing in low-end neighborhoods.
