The Reagan White House moved to lower tax rates for developers in the 1980s and then years of low interest rates glutted downtowns with office buildings. Time's up.
I have a strong hatred for how many storefronts are taken up by "antique shops" (i.e. dusty warehouses full of junk you couldn't give away) instead of actual businesses in the last two small towns I lived in. Makes it so you can't really get that much shopping done downtown.
Don't hate on the antique shops. Hate on the big box stores that everyone goes to shop and has left the only possible business for a small store to become an antique shop.
