Why does TRP assert that women's standards are too high, but that men's can never be high enough?

I know TRP isn't a monolith but GENERALLY i see men claiming it's so hard to get laid, it's so hard to find someone, but they'll only date women 10 years younger then them who are an 8 or hotter. The other guys won't tell them to lower their standards- they'll tell them to perhaps change their own behaviors a bit but honestly, I've even seen a sixty-year-old fat guy told to "never give up" on his dream of wedding an 18 year old virgin.

On a different site I had an argument with an obese and admittedly below-average attractivness guy (who had no intention of losing weight) who also didn't have fame/money or anything other than just general "game" (or so he said). He said he would only date 9s, and was really pissed that none of them would date him. He thought it was okay for him to prioritize conventional beauty standards, but was insulted when women dared to do the same thing. He believed that learning "game" (if he did, in fact, learn it) earned him the right to any and every attractive woman, and those women who turned him down were just bitches. Meanwhile, he wouldn't go near any woman who was actually at his level physically- and had the audacity to complain that it was "so hard" to meet women.

Meanwhile, women are told that if they think it's hard to find a man, it's only because their standards are too high. For the record, I'm pretty middle-of-the-road and I think most people, male and female, could benefit from a reality check, some serious self-improvement and a self-assessment of what's realistic for them, but I wonder why TRP never tells men, "Maybe your standards are just unrealistc" but has no problem saying this to women.

I'm aware that TRP encourages self-improvement for both genders (and I agree with this) but only women are told to be more realistic about their potential partners. Men are told that the sky is the limit.

ETA: A lot of posts about age have come up, which is really interesting, but here's a followup question...if women are so attracted to older men, and it's so easy for older men to pull young women, why are men complaining about a sexual marketplace that is unfair to them? By the sounds of it, men should have it made!

TL;DR why is it that TRP tells women to lower their standards if they want to find a man, but never tells men to be more realistic about only dating teenage 9s?
