Job choice is another factor that determines the amount of pay. Engineers command high salaries, yet relatively few women study engineering. Teaching pays much less and that career field still attracts mostly women. And some pro-business groups say there may be no gap at all. In fact, when you start accounting for these differences, you find the gender pay gap shrinks considerably.
Few people believe the gender-pay gap is zero.
And there is other evidence that women's pay is still held down by discrimination. In high-priced restaurants, for example. One study sent women test subjects looking for waiter jobs. They received half as many job offers as men who were sent in with similar resumes. Discrimination also pops up when orchestras are deciding which musician to pay.
