Deletion of Economic stratification

Comment: Lack of sources is not a reason for deletion, and the deletion rationale does not appear to show evidence of "thorough attempts to find reliable sources" as required by #REASON.  A trivial google scholar search turns up http://scholar.google.com/scholar?q=%22Economic+stratification%22&hl=en&btnG=Search&as_sdt=1%2C39&as_sdtp=on thousands of potential sources.  These seem to establish notability, and the article could in principle (if necessary) be rewritten from any number of such sources
