America's favorite buildings

Results of a new survey regarding Americans' favorite buildings suggest (a) we're not wild about contemporary stuff and (b) we don't think there are many beautiful Catholic churches.  Out of the top 150 buildings, only one (St. Patrick's in New York City) made the list.  Should we care about this?  That is, should we care that we have not (apparently) been building beautiful churches (or, churches that people *think* are beautiful)?
