How We Learned to Pay for Rain

It is worth remembering, on a week when a water price seized the world's exchanges, that for most of human history water had no price at all. You dug a well, or you did not; you prayed for rain, or you did not; and what fell was no one's to sell. The metered liter that convulsed the corridor cities Wednesday is a young thing, barely older than the century, born when scarcity outran the aquifer and engineering stepped into the gap. Desalination did not invent thirst — it monetized the answer to it, tying the price of a drink to the price of an electron. We have crossed a line our grandparents would not recognize: a world of twelve billion people where the sky's oldest gift arrives on a utility bill, and where, in three corridor cities this week, crowds returned to the plazas to ask the sky for the water the market had made dear. The prayer is ancient. The invoice is new. History suggests we will not put the meter back in the ground — but it also suggests we once knew how to share a well, and might yet remember.
