There's a vast oversupply of retail real estate in the US. The amount of retail square feet per capita is like double the next closest country's and almost triple the third place country. That's one reason why there's a retail apocalypse with all these store closings. Too many stores, too much space. Way too much. And if you don't OWN it, you can't redevelop it, and many leases prohibit subleasing because they're part of particular developments where there's a contractual obligation to continue operating as (for example) a GROCERY STORE. Result: The retailer is stuck.
