You have nailed the whole of MBAs precisely. I can’t add to it. Quarterly goals instead of legacy profits kill companies. They are simply a harvest process that goes until the company is too weak to recover. By then the guilty managers have moved on leaving the wreck to someone else.
Sounds a lot like politicians doesn’t it? Thune for example, does not give one whit about improvement or expedience. Time and timeliness do not matter to him, he gets the same result either way. He only cares about his power and money and Thune. Make no mistake, senior management is the same way and they are slick enough to keep their true agenda hidden for as long as they can. The board is clueless or in on the scam.
That's also why so little is new (look at Hollywood's "reboots"). They don't even look at the product or know how it's made: they look at their existing business and simply see where costs can be cut or current product can be recycled to avoid risk and garner profits.
Trump is shaking up this whole manure spreading operation that pretends to be a republican political regime and a first-rate economy, which is why they hate him.
