Our sages explained the verse “Let abundant grain be in the land upon the top of the mountains” (Psalms 72:16).
In the future (the messianic era), wheat will rise up, and grow tall like a palm tree, to the top of the mountains. And lest you say that if wheat will grow this tall the reaper will suffer discomfort, the same verse states: “May his fruit rustle like Lebanon.” The Holy One, Blessed be He, will bring a wind from His treasury and blow across, and this will thereby induce the flour to fall from the stalks of wheat. A man will go out to the field and bring back a palm-full of flour, from which he will provide his livelihood and the livelihood of the members of his household.
There are a few valuable lessons here (besides the ample explanations of earlier rabbis).
Even when there is a huge amount of food available from the massive wheat plants, the man is and the members of his household will be satisfied with a handful
Over eating is a common hazard in today’s wealthy society where food is plentiful. It is interesting that some foods are engineering to be less satisfying, so we eat more of them (the book Salt Sugar Fat explains this). Today often people eat large amounts of food that has little actual nutrition, instead of eating small amounts of nutrient dense foods.
A wise man eats mindfully, and carefully, to get the nutrition he needs without eating in excess.
Another critical observation is that the expectation is the man of the house will go out to the field and bring the flour home to his family. Now if the wheat plans are dropping ready made flour instead of wheat kernels that need to be threshed, sifted, and ground, then why can’t women and children go out and get their own food?
They certainly could. But our sages understood that when the man of the house is seen as the provider, this fosters a strong, healthy family. Therefore, they explained the verse to fit with the reality of human nature. Men are the default providers and supporters for the rest of the family. As a result, the other members of the family respect and appreciate his contribution. This situation worked well for every human society for practically all of human history.
Only in very recent times in western societies have women been encouraged to become fully independent earn their own keep. This is not always in their best interest, as surveys show decreasing happiness among American women since 1950. The increased employment adds tremendously to corporate profits and income tax collections, which incentivizes businesses and government to encourage women to work. This trend is complex and deserves much more analysis.
One of the results of this is that the man’s contribution to supporting his family is considered less valuable and he is less respected in the home. Also, since women seek to marry men who earn more than they do, it becomes much more difficult for a woman making decent money to find a mate she considers suitable.
It is important to note that our sages understood the messianic era will not bring profound changes in normal human nature. We won’t become angels or transcend humanity. People will still be people, but every individual will be empowered and provided for, fostering peace and prosperity.
