Slight correction... it's been self imploding since Steinhaffel took over.
Basically... Ulrich goes to retire perfectly coinciding with 2008 recession pretty much. Steinhafel takes it, eliminates a bunch of positions, and some stores actually saw increased profitability despite recession(not necessarily increased sales - increased profitability...) and the company hasn't moved off of that strategy since. Either eliminating positions or hours any time they can possibly get away with it.
Steinnhaffel would have lasted until 65 (2019ish) had Canada not been such a large blunder. Then the data breach happened and it was gg for his career.
Ulrich was the last CEO target had whose long term vision wasn't simply just "bleed it."
A sad sight to see, but I think the probability of this being the fate of every single successful company gets closer and closer to 100% over time, as you get further and further away from the guy/gal who made it successful dying/retiring/selling. Eventually an MBA who gives no shits about the company except as a means to an end for exclusively selfish purposes takes over and bleeds it AND/OR they don't know HOW to continue to keep it successful, and that's all she wrote.
Retailers this big usually take decades to go out of business. It's not an overnight thing. KMart was going out of business for probably 30 years and hell I still think there's literally 1 or 2 KMarts in the country. Apparently there are now 12. There used to be around 2500. This is Targets' fate. It is a certainty. The only question is time.
Walmart offers a more pleasant shopping experience. For some reason, that perception from the public that Target is better still hasn't shifted. Eventually it will, and then things really start to speed up.
