It's a side effect of having real number feedback on how you're doing. Management can't just make up their own metrics anymore, there is a third party that tells you how well you are doing, and that third party wants to see constant growth or they'll start dropping your price and the financial press will pick up on that and start writing articles about how millennials are killing the rail industry.

It takes real gumption for the upper management to say "screw what the greedy bastards on Wall Street think, we're doing just fine." Especially when their yearly bonuses are tied to what those guys on Wall Street think.
