There are more people leaving this state than moving here. No influx of any group is pushing you out. It’s for profit housing/NIMBYism that failed to meet the demand of the the large group of millennials entering the housing market. There’s absolutely 0 reason to point the finger at tech people when migration to this state is negative. They aren’t raising or lowering your housing prices. With or without the tech industry, housing would be an issue. The “large group” you are referring to are Millennials, the largest generation group in the US, coming of age.

Millennials are the second largest generation ever, and adding them to a housing market which was already precarious for Gen X has absolutely fucked the housing market in states that don’t have much unincorporated land left. Massachusetts has no unincorporated land remaining.
