Macy*s will survive, but very small compared to what they once were. There isn't anyone truly left to purchase them and mall space isn't exactly a top priority right now for retailers. I don't believe they will go under completely as they have a place in the retail world. It simply won't be what customers and associates are used to. Bankruptcy could be in their future, closing stores is for sure. Staffing levels are low now, next 1-3 years could be lower as stores and even square footage shrinks. Workload and moral have to be at a all time low and climbing out of that is a battle in itself, let along sales and credit.
Associates and Leadership are working crazy hours with inventory right around the corner. Then after that comes the news of (more than likely) what stores and positions are no longer needed. This isn't 'wanting them to fail' it's just the current path the organization is on.
