The Perennials

Management professor Mauro F. Guillén argues that the “sequential model” of life — the rigid, one-way path from schooling to career and retirement that working people have followed since the Industrial Revolution — is obsolete and destructive.

Guillén, who also wrote 2030: How Today’s Biggest Trends Will Collide and Reshape the Future of Everything, holds a named professorship in multinational management at the University of Pennsylvania’s Wharton School of Business, where he is Vice Dean of the MBA for Executives program. His online classes have drawn more than 100,000 students.
