Buying a home could prove an economic disadvantage now that mobility is necessary to find new opportunities, but moving is an emotionally trying event, says Caitlin Kelly at True/Slant. "We often choose where we’ll live from a complex matrix of factors: climate, geography, job or educational or recreational opportunities, religious or political or ethnic or racial diversity. We’re not simply extension cords to unplug and re-attach somewhere more (temporarily) useful to an employer," Kelly says. "Moving is disruptive. Disruption destroys communities and emotional ties, no matter how many times a day you tweet or natter on Facebook. Community relies on enduring face-to-face connection, trust and history."
