Vantaggi
Employees are compensated from entry-level to upper management at higher rates than their counterparts in any other company (to my knowledge). Quiktrip employees retain the ability to grow and succeed no matter the state of the nation's economy. Every task done is vital to the company's superiority to competitors, therefore every employee is treated as a vital link to its success.
Svantaggi
A person who starts at entry-level and wants to eventually become Vice President will take about 15 either lateral moves in pay or slight decreases. As a result, many move into entry management where the bonuses line their pocket and stay for the duration of their career. This is the only con; people tend to get settled in a position due to wages, while their potential could have been higher.
