From Bruce Thornton: Western Arrogance and Decline. One quote:
The astonishing wealth of the West, more widely distributed than in any other civilization, the abandonment of religion as the foundation of morals and virtues, the transformation of political freedom into self-centered license, and the commodification of hedonism that makes available to everyman luxuries and behaviors once reserved for a tiny elite, have made self-indulgence and the present more important than self-sacrifice and the future.
Declining birthrates, a preference for spending on social welfare transfers rather than on defense, and a willingness to beggar our children and grandchildren with debt in order to finance these entitlements– all bespeak a people whose wealth deludes them into thinking that they can imprudently ignore the future and indefinitely afford these luxuries that in fact insidiously weaken the foundations of our social and political order. This process is more advanced in Europe than in the U.S., but we in America have been steadily moving towards the same mentality.
