Why would it? Even in the most cynical business sense, a business will spend as much money on employees as they must. Again, assuming maximal cynicism, they won't care if it's salary or "ports", as long as it's the most effective buck they can spend (think ROI).

What is effective in attracting employees depends, at least partly, on what employees want. That might be either some amount of money into ports or more salary. Paying shareholders more will not attract employees.
