It's all relative. Someone making $40K/year is going to be HEAVILY incentivized by a higher salary. Someone making $400K less so. There are plenty of people here on HN that have made enough money that they could take a 50% pay cut and not have a significant change of lifestyle. These ones are pretty unlikely to salivate over a job offer with a higher salary.
