Ok, lets look at this another way. Say the average salary for a cashier is X at one store. However, Sally gets paid Y while Harry gets paid Z. Turns out, they have similar qualifacations and background, along with salary history. Both accepted a raise when they took the job at this store, but for whatever reason Sally gets paid more - and has since the beginning. Similar differences are found between other employees. As one of the reforms, the company starts publishing every employees' salary. A few folks, like Harry, are understandably upset. To help remedy this, the company raises the pay of some folks to make things more fair between folks with similar qualifacations, and make company-wide standards for getting paid more. After a while, that average wage, "X", gets higher because folks are getting paid more.
