It’s a complicated issue and there can be many outcomes. I’m going to assume something close to the “canon” setting (monster-girls give birth to incubi and MGs at 1:1 ratio, except cases like khepri and devil bugs; “vanilla” MGE setting preserved, no special extra-lore assumptions are being made)
Short answer: A world that rewards the strong and aggressive. Competition will be intense and omnipresent, and you’ll have to struggle every day in order to have a chance to improve your life or even to keep what you have. Most humans would agree it’s a utopia, though.
Longer answer: The “all-female monsters” was a
humongous reason why MGE is a “hug-box”. When you’re surrounded by lusty women, all of whom love you regardless of your social status, appearance, origins etc. you basically have zero competition. The amount of MGs is only going to increase over time, and so is their proportion relative to men, resulting in overabundance of intimate partners and reducing all competition between men in this area. Restoring the gender ratio back to 1:1 will bring back scarcity of women and, in turn, competition for the right to mate. Which, consequentially, will lead to the creation of a sort-of ranking system used by MGs to determine which man is a better mate-for-life.
This, in turn, will lead to a hierarchy. Obviously, a higher-tier woman will have more freedoms regarding the choice of her man, and vice-versa, more successful men will be more desirable, leading to them having greater freedom of choice. Naturally, both men and women will tend to pick the best matches for themselves; in other words, the best pair with the best. Then the second-best with the second-best, the third best with their counterparts etc. While not immediately apparent, this will result in yet another interesting development:
Stratification. You see, in human society, your personal capacities such as strength, intellect, charisma etc. are a result of purely random events which are poorly understood (though some tendencies can be identified). Being a king does not give you a huge advantage over some peasant since it’s a purely social status; it doesn’t give you better traits. It’s a lot different in a society where your qualities, and the qualities of your offspring, are largely determined by the amount of mana and power you have,
which are expected to be the primary dividing factor in a monster society.
That all means: A big, strong guy, who has fought and bullied other men to get a matching wife (say, a lilim, wight or a dragon) will have a lot more power (especially if accounting his wife) than one of the said less-fortunate men. This mana, power, what have you, gets passed onto the offspring, and there is a very good chance that at least one of their kids will become stronger than their parents. The less-fortunate men and their wives simply cannot afford enough mana to keep up in this evolutionary race, let alone catch up with them, and this gap will widen with each successive generation. This will result in stratification of the society, which will only worsen as time passes. Exactly what will happen to the society and how will it transform, accounting all the monster mana fuckery, is hard to say. Of course, that won’t stop the competition, since the best will still rival the best, and the other strata will have enough internal struggles to keep them occupied.
All in all, those who will succeed and prosper in this new world are the strong, aggressive, assertive men and women. Traits like intellect and creative inclinations will most likely
not help you secure your place, simply because a buff, overpowered guy who can punch your brains out is generally more effective in short run than some techno-magical enthusiast that might spend months, or even years, inventing some powerful machine that would allow them to outperform the musclechads. Well, that’s not a problem for the absolute majority of the humanity, so those few mentally-inclined individuals would likely want to focus their efforts on fleeing the Brave New World unless they want to slowly decay.
