Variation of Exercise $6\mathrm{.}9($based on an edited version$)$:

A store manager observes that the loyalty of employees in her company is low. She thinks that if their working conditions are improved, pay scales raised, and the vacation benefits made attractive, employee loyalty will be boosted. She doubts, however, if an increase in pay scales would increase the loyalty of all employees. Her conjecture is that those who have supplemental incomes will just not be $$turned on$$ by higher pay. Finally, providing employees with more attractive vacation benefits will make them happy, with a resultant boost in loyalty.
