I always kind of assumed there was a constant gentrification effect in cheap NYC neighborhoods because young people are price sensitive, no matter what their race or profession. Ethnic neighborhood is cheap -> Young professionals start to move in -> Integration begins -> Businesses that cater to young professionals establish themselves in the neighborhood -> Landlords slowly but steadily increase rent -> New immigrants and children of existing ethnic tenants move to a different, less expensive neighborhood
