Let's be clear who expects this: women do.
Most women will stop dating a man if they discover he makes less than they do. When I was still in the Bay Area I was on match.com for a bit. >90% of the women's profiles stated they expected their match to make more than they do (even having this information in the form felt a bit weird for me).
And no, this is not because of the "pay gap", which is a myth, or because they can't. In fact, the unwillingness actually increases with income levels, so the women who could most afford it are least willing to date a guy who makes less than they do.

I'm saying it is irresponsible to advice boys to make live choices that are at odds with female mating behaviour, because it adversely affects their life outcomes.
Your comments read as weirdly patriarchal, and dont reflect at all close to my experience with women.
Here is just one study I quickly dug up, there are others confirming this: https://www.sciencedirect.com/science/article/pii/S016726811...

I don't understand whats patriarchal about my comment, care to elaborate? If you have a more solid data point than "thats not my personal experience", I'd be certainly interested in it.
>>> I don't understand whats patriarchal about my comment, care to elaborate
I mean seriously, the answer is in your own comment.
Edit: I don't understand the downvotes.
His own comment implies income is an important factor to attractiveness for men then asks why is that a patriarchal thing. I'm not being patronising but it's obvious that it's expected for the man to be the bread winner which is patriarchal in nature. The man doesn't have to be the bread winner.
Why isn't a high income woman attractive?
