Why do you work where you do?

A friend recently asked this question and we came up with a short list of answers:

1) Passion - You love the work you do
2) Loyalty - You believe in your company
3) Job Stability - You feel your job is safe and protected
4) Money - You can't earn as much elsewhere
5) Options - Haven't found anything better

It could also be a combination of those. Did we miss any?

This friend was basically saying his reasons were #4 and #5 but he wasn't looking to know if his these reasons were true. I think as an employer, you should want your employees in the first two categories. I can't imagine anyone working better than if they have a passion for what they do and believe in their company. Its what all employers who look for high retention should aim for, right?
