Roots also cause community, and make people more likely to organize to protect and improve the conditions of the place where they live.
edit: As a simple illustration, I am a typical single, firmly middle class professional who lives in a neighborhood that I have no connection to, is nowhere near any of my family, and I know maybe one or two of my neighbors by name. If the city decided that it wanted to dump all of its garbage in the middle of my street, end rodent control, fire, and police protection in my neighborhood, and add heavy metals to the water, I would just move to a place where they weren't doing that, and leave the people who couldn't afford to to rot.
As one of the members of the top 10% in household incomes, I could conceivably keep doing that until 90% of the populace was mutating in a nuclear wasteland, and I was reduced to a shitty studio apartment for $6000/mo in the outskirts of a walled community guarded by our private paramilitary massacre-rape squad, which periodically makes incursions into the wasteland to seize kitschy furniture to sell to us on the inside.
