Male and female provide different goods and services in relationship and marriage, they should be judged by different standards. Most feminism/MRM theories are flawed because they ignore basic economic laws and biologic reality, view every difference between two genders as “unfair”, “sexism” or “Gyno-centrism”.

Use start-up as example, investors provide capital while entrepreneurs are in charge of the company. Their roles and responsibilities are different, investor may spend no time on company, but entrepreneurs could not “equally” to do so. Sometimes one side in the deal could get extraordinary return rate, like Jeff Bezos’s wife or investor, fair or unfair, the reason should not be “his early investor did nothing important!” kind of nonsense.

Reproduction process is the most important difference between two genders. In fact it might be the only one, because most gender difference are caused by reproduction. In other species with different reproduction investment pattern like seahorse, we could see different gender roles and behaviors. Naturally, female human need to invest more in reproduction, thus require proper compensation.

In another perspective, female reproduction ability is scarce and worth a lot while male reproduction ability is too abundant and almost not worth anything. One could say female human are born with a valuable skill(reproduction) or a lot of property (her body), while male has lower value if not better enough in other aspects. Personally, I believe in a modern society, the work ability of female human are on par with male human, so in general male human are biological inferior.

One may ask, in a world with contraception, why male need to pay more in date? Because our preference are not evolved for modern technology, human still afraid of snakes although many people never seen them, most male still fear his children are not truly his although we have paternity test. I do believe we should fight against these unreasonable instinct to get better deal, for example male should be more tolerate about cheating, but clearly most people are not that smart.

Many people don’t understand gender difference. They only see their gender disadvantage while ignore their gender advantage. In a fair relation or marriage, male human SHOULD pay half of the price difference between his body and his partner’s body. Here I want to stress this is not traditionalism, male human could pay the price with combination of money, appearance, sexual ability, emotional value, loyalty, house work, marriage citizenship or anything valuable. “The Northern Europe model”, at least as many people understand it, is very unfair to female human because they don’t get enough for what they paid.
