"So basically you're saying that if a family has lived in an area for many years (possibly several generations), and are gradually being priced out of the ability to exist and work, they should just move on somewhere else, breaking long established ties with friends and family?" You do realize you live where you do solely because this has happened in the past, right? "That's pretty harsh and selfish outlook about the lives and welfare of working families who will never see anywhere near the six figure salaries being earned by FB, Google et al engineers." I do not consider it a harsh and selfish outlook that people should try to live where they can make ends meet. My parents did it. My great great grandparents did it too. I did it myself. People move over time. Some generation in your family moved for exactly this reason. Probably many. There is literally no way everyone in the world can afford to live in the same area. It is not an viable proposition. The fact that people before you lived somewhere gives you no more right than the next guy to live there.
