Corporations won't spontaneously pay more for labor any more than they would spontaneously pay more for parts or raw materials. If a corporation chooses to spend more on expenses, then it will tend to spend on things that increase its value. Those things may include spending more on advertising to bring in new business or moving to a fancier office to impresses new clients. Paying more for labor, however, is like paying more for electricity; it doesn't add any value.
