Quote - F. A. Hayek

"while for the immediate improvement liberalism had to rely largely on the gradual increase of wealth which freedom brought about, it had constantly to fight proposals which threatened this progress. It came to be regarded as a "negative" creed because it could offer to particular individuals little more than a share in the common progress - a progress which came to be taken more and more for granted and was no longer recognized as the result of the policy of freedom. It might even be said that the very success of liberalism became the cause of its decline. Because of the success already achieved, man became increasingly unwilling to tolerate the evils still with him which now appeared both unbearable and unnecessary."
