But the twenty-five poorest countries already spend twenty percent of their GDP on water. This twenty percent, about thirty cents, ain’t much, but do the math again: four billion people spending thirty cents a day is a $1.2 billion market every day. It’s $400 billion a year. I can’t think of too many companies in the world that have $400 billion in sales a year. And you don’t have to do a market study to find out whether there’s a need. It’s water. There’s a need!
