Another tangible benefit of reinstating polygamy insofar as the age gap crisis is concerned, is that while AZ’s close in age solution is also working towards the solution, that avenue ONLY helps future, young, singles. Whilst reinstating polygamy, in addition to helping current young singles, ALSO helps all the OLDER single girls who the future close in age marriages are too late to benefit from.
So both AZ’s idea’s and polygamy can work hand-in-hand in helping close the shidduch crisis.
