I am starting to think it is a part of the management cycle. They new batch feels confident they can do X so they have to re-learn, while inflicting ridiculous amount of pain the process.

Two years ago, one former exec at my place was perfectly happy to throw resources ( his word ) from India at a problem, while unwilling to pay the vendor for the same thing. I voiced my objection once, but after it was dismissed I just watched the thing blow up.

I am not saying current situation is the same. It is not. But, it is the same hubris, which means miscalculations will happen ( like with Dorsey's Block mass firing ).
