That has to be the most self centered approach to this issue I've ever seen. Really? You think you helped alleviate a housing shortage? The psychology of your post is frightening.
Your misunderstanding of economic principles is the frightening part.
A housing shortage in an entire region is the sum of thousands, and hundreds of thousands of individual decisions. Our personal move didn't do a lot but the sum of similar decisions by many, many individuals does have an effect.
My point was that the societal changes brought about by purchasing on the internet as opposed to in local stores does make it easier for people to move out of congested areas when their livelihood no longer depends on being in that area. Reducing the incentives to stay in a congested area absolutely does alleviate a housing shortage.
I view this as a net positive for the county as a whole.
As far as "frightening psychology" goes, using a personal example as a literary device is common practice.
