Jews are winning too. Jews are absolutely winning. Should we be like jews because they are winning? No, because it is a degenerate strategy that results in corruption and kiddie fucking and a total lack of egalitarianism and peace and prosperity. Inherently both are opportunistic strategies that only work when there are more prosperous societies they can exploit. They generate lack of trust in the system as a natural consequence of how they work. Technically what you have described above is matrilineal polygamy, which is more african than middle eastern. But let’s stick with “based” patriarchal polygamy so I can tear it down and show you what its really about. In patriarchal polygamy the most reproductively successful males are the wealthiest males, the horniest males, and the most aggressive males. These men tend to have traits for wealth hoarding/greed, rapey-ness and violence. Unlike high status males in monogamy, they are 2x, 3x, 4x or more as reproductively successful as mid status males. That means all their traits for wealth hoarding, rape, violence are spread disproportionately in the next generation. Lower status males are incels that have no reproductive success at all on average. Soon the only males left in the society are descendents of rapey violent alphas. Female hoarding causes a constant scarcity of women for middle and lower class males, especially young males with no $$$. Males constantly fight with each other over the scarcity of females. Islam sublimates this problem by encouraging low status males to invade other lands and steal other people’s females to marry or rape (both allowed). Even low status males have rapey alpha lineage so this suits them. The males are so busy fighting over spoils and women that they do not spend much time actually producing wealth. There is no trust between men since violence, theft and corruption are the rule, and greedy violent get the most females. There is also an arms race among high status males to hoard the most young females, so age of bride and difference in age between groom and bride goes down the more polygamy is practiced. Kiddie fucking is the natural consequence of patriarchal polygamy, not just islam. It happens everywhere you see patriarchal polygamy: child brides. Monogamy forces males to only have one female, so extremely greedy, horny, violent men are not terribly reproductively successful compared to patriarchal polygamists. This encourages egalitarian traits, high trust between males, and non-violent competition between males in wealth production: working hard and having skills. There are effectively no incels. Females have higher bargaining power because males have to get the highest value female they can— they can’t compensate for one high value female with two lower value females. This results in “chivalrous” behavior in males, basically unknown in highly polygamous regions. Marriage age of females is high (~23) and age difference between bride and groom is smaller. Monogamy has a bunch of package traits like prosperity, high trust, no incels, egalitarianism, low rape, low kiddie fucking, relatively high status for women. Islam and patriarchal polygamy have another package. After a small number of generations, corrupt, rapey alphas flood the gene pool. That is why all the child grooming gangs in Britain were muslim and not hindu. You can breed for kiddie fuckers in just a few generations. Polygamy, whether you implement matrilineal or patriarchal forms, ends in low prosperity and low trust. It is an evolutionary certainty. If whites do not continue to follow monogamy, they cease to act like whites. An evolutionary mechanism triggers a genetic shift. TLDR You can’t pick the things you like from polygamy and leave the rest. The whole shitshow comes home to roost.
