Have you ever told a friend that and them respond with something along the lines of, "You know, I'd never thought of that. I'm just going to go get a job. Thanks!"?
Me neither.
Me neither.
I also don't know anyone in a similar situation who isn't acutely aware of the situation - they don't need their friends constantly giving them the most obvious advice in the world, they need support.
I'm also not really sure why you're playing this card, since I referenced other people in my previous comment... but oh well.
Your friends may very well all fall into the category you describe. There exist nonzero scenarios where people don't.
