Schopenhauer

"[L]ife presents itself by no means as a gift for enjoyment, but as a task, a drudgery to be performed; and in accordance with this we see, in great and small, universal need, ceaseless cares, constant pressure, endless strife, compulsory activity, with extreme exertion of all the powers of body and mind. Many millions, united into nations, strive for the common good, each individual on account of his own; but many thousands fall as a sacrifice for it. Now senseless delusions, now intriguing politics, incite them to wars with each other; then the sweat and the blood of the great multitude must flow, to carry out the ideas of  individuals, or to expiate their faults. In peace industry and trade are active, inventions work miracles, seas are navigated, delicacies are collected from all ends of the world, the waves engulf thousands. All push and drive, others acting; the tumult is indescribable. But the ultimate aim of it all, what is it? To sustain ephemeral and tormented individuals through a short span of time in the most fortunate case with endurable want and comparative freedom from pain, which, however, is at once attended with ennui; then the reproduction of this race and its striving. In this evident disproportion between the trouble and the reward, the will to live appears to us from this point of view, if taken objectively, as a fool, or subjectively, as a delusion, seized by which everything living works with the utmost exertion of its strength for some thing that is of no value. But when we consider it more closely, we shall find here also that it is rather a blind pressure, a tendency entirely without ground or motive."
