Someone with more income might exchange more money for time/comfort, if all things are held equal including the price.
I think the inverse is true when you consider exchanging things other than money for more comforts.
That is to say, people will pay more money because they have more of it the higher their income (because the marginal value of each dollar goes down)
Asking would you be willing to risk your life for more comfort, that answer changes. The higher your income/comfort/happiness, the less willing you are to risk your life for more comfort.
The less people have to work, the less they are willing to risk their lives for more free time.
Who would risk death protesting for more leisure: someone working 80, 40, 20, or 2 hours?
