Talk a walk on the South Side
As I was driving down East Carson Street last night, I noticed that Rynn's Luggage, near 19th Street, had closed. But fear not, loyal Rynn's customers--it turns out it is merely moving a few blocks down the street to the new SouthSide Works. Now, there is nothing out of the ordinary about a business changing location. Businesses need to go where they can maximize profits. It's possible that they've needed a better location for quite some time, and the new SouthSide Works will give them newer digs while remaining in the same part of town.
Unfortunately, SouthSide Works might not exist were it not for the subsidies its developer received through the Pittsburgh Urban Redevelopment Authority. And when retail development occurs absent an increase in the local population or its buying power, then existing stores and retail districts will suffer. And let's not forget that the promise of all the region's subsidized retail complexes is that they will bring in new businesses, not poach existing ones.
You know, the free market, while messy, works pretty well most of the time. This city might want to look into it.
