Passage... "Results not causes."

A passage from The Grapes of Wrath by John Steinbeck:
"The Western Land, nervous under the beginning change. The Western States, nervous as horses before a thunder storm. The great owners, nervous, sensing a change, knowing nothing of the nature of the change. The great owners, striking at the immediate thing, the widening government, the growing labor unity; striking at new taxes, at plans; not knowing these things are results, not causes. Results not causes; results, not causes. The causes lie deep and simply- the causes are a hunger in a stomach, multiplied a million times; a hunger in a single soul, hunger for joy and some security, multiplied a million times. The last clear definite function of man- muscles aching to work, minds aching to create beyond the single need- this is man."

Wow... John Steinbeck is a great author. I just love his writing... it's really powerful. He wrote this in the Great Depression so it makes total sense.
