The authors argue that rather than eliminating borders, globalization has actually multiplied them, creating new types of boundaries that operate at various scales - from local to transnational. These borders are not just physical but manifest in economic, social, and digital realms, fundamentally reshaping how societies function.

The book explores how modern borders influence labor markets and migration patterns, demonstrating how they create distinctive zones of labor exploitation while simultaneously facilitating new forms of worker mobility and resistance. This dual nature of borders both constrains and enables various forms of human movement and economic activity.

A critical examination of how border proliferation affects traditional concepts of state sovereignty and citizenship. The authors show how borders have become instrumental in redefining political power, creating new forms of governance that challenge conventional understanding of nation-state authority.
