There are a lot of post office branches that could be closed and returned to the tax rolls. Would business really be hurt if postal service was reduced to 3 days a week? I doubt it. The private sector could pick up any priority mail.
When they abandon them, and the leases run out, the value of the buildings will be dramatically reduced and the property tax rates will be adjusted appropriately.
So much for "returning them to the tax rolls".
BTW, my number "28,000" is much better than the USPS number of "3,500" because it was done with an eye only to operational needs ~ not political expediency!
I would think that IF it saved a whole heck of a lot of money, going to 4 days a week would be acceptable, as long as it comes along with less pay and fewer workers, which with govt isn’t always the case...
