[The "Moving To Opportunity" study group’s] special mobility assistance didn’t enable families to gain and sustain access to high-opportunity neighborhoods. Although many moved to better housing in safer neighborhoods, few moved to neighborhoods served by high-performing public schools. And few spent more than a year or two in low-poverty neighborhoods. Rising rents, problems with landlords, and difficulty finding the next apartment all pushed families back to less desirable neighborhoods.
In other words, they didn’t really move to opportunity. It turns out that helping low-income families find, afford, and hang on to housing in high-opportunity neighborhoods requires more help than anticipated. Building on the lessons of MTO, mobility assistance programs in Dallas, Chicago, and Baltimore are now offering more hands-on help (with both the first move and subsequent moves) so families they serve can move to and stay in safe neighborhoods with good schools and abundant opportunities for both kids and adults.
It seems to me that helping low-income families move to greater opportunities requires governments to spend more money providing and sustaining supportive infrastructure (parks and libraries) and truly public schools. Also, without some sort of regulations on the apartment market, I don't see how working-class families will survive higher-income neighborhoods, where the atmosphere is more of a free-for-all than fair-value.
