Tend to be a little bit more cool and daring. Beautiful stuff can get boring after awhile. The Old World, for instance, can easily get very boring after being there for a while. Living in America tends to be more awesome because we're not stuck in the Old World mentality that easily.
All things equal and being practical who buys an ugly car, ugly house, or ugly pet just because they are "sufficient"? Efficiency means nothing without being aesthetic; form has almost always triumphed over function (thus why we have clothing fashions and art as a species) since that beautiful golden spiraling wonder of a paperweight is equivalent to a dirty little rock outside that would cost no time, no effort, and no energy to really replace the sculpture.
