I think while this point of view is indeed very true for the large majority, larger companies combat this job hopping, by encouraging internal job switching; ie. going from one area of business to another, which is closer to getting a new job, than getting a promotion. This ensures that the company doesn't waste time in getting a ext. employee to get accustomed to the culture. But that's really the essence Human Capital Management (HCM).
