Sears
Suffered from the same malaise which brought so many once great US firms to their knees in the last few decades:"MBA" syndrome.
It's proved more fatal than the earlier form, Merger and Acquisition Fever.
Nothing to be done about it, it just has to run its course.
Pity, as so many have pointed out, Sears should have been Amazon. All the parts were there.
Oh, well. Does anyone remember the vitriol over Maytag here at their demise? We were all screaming at each other (just for the record, those of us saying the rah-rah 'muhricans were wrong and Whirlpool would fire everyone were, sadly, right).
We were screaming over what was already a dead corpse. Maytag had already become plastic-fantastic junk.
Same with Sears - there's no there, there. I went to the local Sears automotive with a friend a bit back. They actually told here they didn't know whether they could get tires for her 'furin' car.
A Honday CR V.
Seriously.
When you reach that point, it's time to shovel the dirt over you.
