The only exception is if you're 15 years old and it's literally your first job, and in that case it's probably appropriate that the offer is for minimum wage.
So, if I'm 21 and graduating from college, I'm supposed to have enough saved to be able to turn down that first offer? I don't know about you, but I worked >50 hours / week in college (making between $10 - $20/hr at various jobs in early 2000's), and I barely kept the tuition bills paid. Granted, I basically had no debt coming out of college, which put me ahead of a lot of my peers, but I wasn't in any position to say no to a job offer and live on my luxurious (non-existent) savings.
Now that I'm ~15 years out, I do have the freedom to turn down job offers, but it's because I started out with no debt and have been able to save. For those starting off in the hole, saying "no" is a luxury they won't have for a LONG time.
