Every girl is scary! Now I understand why men are usually more afraid in these reverse worlds
from what we've seen, that's not so much the case in this setting; the guys are all (at least as depicted) more hedonistic and sorta cold/callous toward women.
The 1:39 series
does have boys that are super afraid, but even that makes more sense, as the
extreme ratio disparity would, I think, reasonably lead to women being
very aggressive to try and secure a partner, because increased scarcity promotes more desperate struggles to acquire that resource.
Which means women would become outright predatory, when they have some 40ish rivals for the same partner.
In this setting, it's more like men just get their "pick of the crop", as it were (gross to say, but kinda fitting in the way women are treated in this setting, so). They can afford to be choosy, and don't have to check themselves because if one chick's turned off by their self-interested behavior, there's always another one in line waiting her turn.
So men are almost encouraged to be selfish and arrogant in just doing what they want, because while there's less discrepancy, it's still noticeable enough that women can't afford to have the highest standards when there's a reasonable chance it means they're Forever Alone - so there's no "check" on behavior for men.
