• Overall strategy of the organization: Does the company need the best people or can they be average?
• Overall ability of organization to pay: Startups might be only able to pay less money, if not money organizations need other options (stocks, a vision)
• Ability to attract and retain employees: Hard if there are good alternatives/competition for workers
• Strength of union influence: If they exists, they may have a strong influence

May be able to pay less with high job security or good benefits and vice versa. The overall package is important!
