I see your point and this seems to be our main difference on exactly that. Magnitude.
I will agree that there is some difference, but not to that extra-ordinary magnitude you mention.
For the following reasons:
a) The appearance of every person is very important in school, church, work, in transit, on a night out, everywhere. Let’s not forget that for the vast majority of the people we meet, the first impression is usually our last (because we do not meet most people more than once) and if you are not attractive you will see more people for the last time than most 
b) Such a vast difference is not supported by data. Men do not care about their appearance? Since when? Let’s only take the simple thing, clothes:
Women seem to spend more. Around 40% more. Even taking into account the possibility of difference costs in the two industries, I will agree that the numbers say that there is a discrepancy, but not on the level of “poor and billionaire” …
And then it is the gyms:
I quote:
“One might assume that majority of gym members are male; however, statistics show this is no longer the case. More than half—50.5%—of gym-goers are now female (IHRSA, 2020).”
So, it is fifty fifty there … hmm, so, no difference there?
Anyway, the overall difference seems to be very far from the magnitude you described.
There are multi-billion industries that live off the natural urge for people to be attractive (not to mention the billions spent into marketing to inflate that natural urge 
), especially to the opposite sex/gender they wish to attract.
It is definitely not a one-sided effort.
It is not a matter of determination. Just not the same words, sorry.
That’s why we have two of them.
Great choice of words there.
You might be surprised, but that might also apply to you as well.
The difference is, I am not trying to convince anyone. Never tried it in 20 years of foruming and I am not about to start now.
I’ve said it before and you can “hunt” for that as well … a discussion is useful to explore other points of view and re-consider your opinions according to the new data you get. It is not there to “convince” other people.
The way I see it, everyone is holding a piece of the valuable and complex puzzle of truth.
Arguing is not a tool for convincing and thus losing that piece. It is a tool for finding what other people think and seeing that puzzle piece.
Don’t believe me? Well, I’ve got the receipts for that with “the Relative and the Absolute”, since you like digging in the past:
Even in my wildest dreams I cannot write as profound texts as Papanoutsos, so I suggest you give it a try. It is one of the best texts ever writen imho.
As far as I am concerned I have read in this topic dozens of new ideas and points of views and I find all of them quite fascinating and I want to thank everyone that gave their time to present their valuable opinions.
For me it was a very useful topic. I hope other people will find use in the new/different data and new/different ideas presented.
