An excerpt from Robert Heinlein's TIME FOR THE STARS

We got interested in the purposes of the Long Range Foundation. Its coat of arms reads: "Bread Cast Upon the Waters," and its charter is headed: "Dedicated to the Welfare of Our Descendants." The charter goes on with a lot of lawyers' fog but the way the directors have interpreted it has been to spend money only on things that no government and no other corporation would touch. It wasn't enough for a proposed project to be interesting to science or socially desirable; it also had to be so horribly expensive that no one else would touch it and the prospective results had to lie so far in the future that it could not be justified to taxpayers or shareholders. To make the LRF directors light up with enthusiasm you had to suggest something that cost a billion or more and probably wouldn't show results for ten generations, if ever ... something like how to control the weather (they're working on that) or where does your lap go when you stand up.
The funny thing is that bread cast upon waters does come back seven hundred fold; the most preposterous projects made the LRF embarrassing amounts of money—"embarrassing" to a non-profit corporation that is. Take space travel: it seemed tailor-made, back a couple of hundred years ago, for LRF, since it was fantastically expensive and offered no probable results comparable with the investment: There was a time when governments did some work on it for military reasons, but the Concord of Bayreuth in 1980 put a stop even to that.
So the Long Range Foundation stepped in and happily began wasting money. It came at a time when the corporation unfortunately had made a few billions on the Thompson mass-converter when they had expected to spend at least a century on pure research; since they could not declare a dividend (no stockholders), they had to get rid of the money somehow and space travel looked like a rat hole to pour it down.
Even the kids know what happened to that: Ortega's torch made space travel inside the solar system cheap, fast, and easy, and the one-way energy screen made colonization practical and profitable; the LRF could not unload fast enough to keep from making lots more money.
