flu, think about what you just wrote. There is NO correlation between performance and pay.
C’mon, you are smarter than that.
It may be that there is too little correlation, it may vary by company, profession, etc. But companies that pay and promote by performance tend to do better than their competitors who don’t and thus trounce them in the marketplace. Not always, of course. But that is the general tendency. That’s also what makes capitalism so annoyingly productive to its detractors.
