There are pretty heavy countervailing forces in favor of standardized salary bands for everyone. Employees compare notes; it can be demoralizing to hear that the company thinks your teammate is worth 20% more than you, and it instantly leads to politicking as everybody else asks for raises. While in the eyes of the business owner there may be clearly some employees that generate more value than others, good luck convincing all the employees that some of their teammates' work is more valuable. This tendency is more pronounced in bigger companies (where performance is more illegible), but the problem with small companies is that there are wide variations in their profitability and hence their ability to offer high salaries (and this is usually less than what big companies offer, hence their ability to get big). Job-switching here is the economy doing its job and funneling resources to the activities that generate the most consumer value.
