Prices are a function of supply and demand, including how much buyers can afford to pay. How much buyers can afford to pay is a function of profits.

A business with higher profits per employer can afford to pay employees more, but that does not mean it will, since prices are still subject to supply and demand.

Whether or not it is a salary or bonus does not matter, it is all part of the price the business pays for the labor.
