Famous quotes containing the word control:

    There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been “Let every man look out for himself, let every generation look out for itself,” while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.
    Woodrow Wilson (1856–1924)
