Savage 78, I find the whole notion of pre-nups distasteful, I find your paranoid attitude towards women distasteful as well. You have claimed to be very well-off, and perhaps that has coloured your attitude, as I imagine the very rich may be more likely to attract partners more interested in money than love. You casually insult all women with your ideas about the handsomeness of your children and the protection of your estate from the woman you claim to love (as if as soon as a marriage breaks down, every woman turns into a hateful snake, which is patently untrue).
I notice twice you have referred to keeping your assets intact for your eldest male heir, another old fashioned, mysoginist, cruel practice, which over the centuries has led to much hardship for children not fortunate enough to be the favoured first male. (I can look to my own immediate forebears, where the assets were land, not money: the oldest male got all the land, and the rest of the children were forced to struggle, the children of farmers with no hope of obtaining enough farmland to practice the living they were raised with, despite the endless labour with which they had supported the very farm now owned by their eldest brother).
I would not marry any man who even suggested a pre-nup, regardless of whether he or I was the richer person, as I would assume he had no real love for me, no real trust in me, and a lousy opinion of women in general. We have courts in my country which oversee division of assets in the event the parties cannot agree: there is no 'alimony' here, only child support, and the overwhelming evidence is that women and children suffer from divorce far more than do men, who often make more money after the divorce, except in cases where the man takes child custody, in which he is more likely to suffer financially.
