<P> The original German term is stahlhartes Gehäuse ; this was translated into `` iron cage '' , an expression made familiar to English language speakers by Talcott Parsons in his 1930 translation of Weber 's The Protestant Ethic and the Spirit of Capitalism . This choice has been questioned recently by scholars who prefer the more direct translation : `` shell as hard as steel '' . </P>
