I have worked in corporations where senior leadership has implemented the "internal competition" mindset. It was horrible. The learned behavior by lower-level leaders is like cancer - almost impossible to eradicate without firing a lot of people. The energy dissipated in internal fighting and one-upmanship is utterly amazing and leaves you mouthing "WTF?" more times than you can remember.

Coming soon to a business website near you: Employers complaining about how employees have no loyalty and want too much money... This reads like a pile of BS spouted by a frustrated employer unable to find experienced people willing to work for peanuts. In 3 years' time that employer will probably be haemorrhaghing employees and whining still more loudly, still failing to connect the dots.
