This book examines the ways in which our ideas about language and identity, which used to be framed in national and political terms as a matter of rights and citizenship, are increasingly recast in economic terms as a matter of added value. It argues that this discursive shift is connected to specific characteristics of the globalized new economy in what can be thought of as "late capitalism". Through ten ethnographic case studies, it demonstrates the complex ways in which older nationalist ideologies which invest language with value as a source of pride get bound up with newer neoliberal ideologies which invest language with value as a source of profit.
