I'm not travelling down the road of socio-economic discussion, but I respectfully submit that you really have to know and understand the many details, nuances and unusual nature of the lower Cape Cod economy. I once lived there year round for a few years, so have at least
some personal insight.
For starters, bear in mind that a whole lot of Provincetown (i.e., virtually
all of the land east of Route 6) is owned by the U.S. Dept. of the Interior / NPS / Cape Cod National Seashore. There is
no housing there --- and there never will be. The remaining bit of Provincetown (on 1A / Commercial St., Bradford St and the short offshoot streets) has a
very limited amount of residential property, much of it used as seasonal "vacation" property, all of it very expensive and mostly unavailable to locally employed year round residents (both literally and financially). Nonetheless, Provincetwon has a Police Department, a Fire Dept (and until recently, its' own high school) to support. It's very hard to draw cops, firemen, teachers, etc. to a town where they can neither afford nor even
find year round housing. The adjoining town of Truro has, over the past few decades, essentially become a haven / enclave of seasonal homes for the uber wealthy (much of Truro and most everything east of Route is also part of CCNS, btw). Ditto for much / most of the land in Wellfleet east of Route 6. It's a unique situation and a real dilemma, the likes of which I have not personally witnessed before or since living there. I was fortunate to have acquired a (overpriced) long term rental in Wellfleet when I accepted and worked a job on the lower Cape for a few years. Despite the ancillary problems, I am personally grateful that President John F. Kennedy initiated creation and preservation of the Cape Cod National Seashore, making that land and beaches available to everyone, not just the uber wealthy who would surely have turned it all into gated, private vacation property. Good on 'ya, JFK!
In any event, I'm frankly glad to see that a limited amount of new, affordable housing will become available to year round residents there as a result of the unfortunate (and eminently avoidable) saga / debacle of the grossly mismanaged timeshare property known as Harbor Hill.
