Pay—the reason most humans work—remains a major motivator today. When consulting firm McKinsey earlier this year asked workers why they took a new job, nearly all groups gave the same No. 1 reason: More pay.

Getting a new job is usually the easiest way to get a raise, with pay for job switchers consistently rising faster than for those who keep the same job

Correct me if I’m wrong, but I have the very slight suspicion that it’s not actually the workers to blame for not staying at a company their whole life.

Exactly. I'd bet good money most people don't get enjoyment out of job hopping, but it's almost necessary these days because companies have become increasingly disloyal and stingy towards employees.

If companies would just offer decent raises, meaningful career progression, and two-way loyalty, I'd bet most folks wouldn't job hop at all!
