Tim Costello has died. He was an ardent fighter against globalization and it's glorified labor arbitrage agenda.

Mr. Costello was hailed by many academics and labor advocates as a bona fide worker-intellectual. A genial, mustached native of Boston, he drove fuel-delivery trucks, worked as a lobsterman, founded a group that battled against the fast-growing use of temporary workers and developed close links with labor advocates in China, Italy and Mexico.

His most notable book was “Globalization From Below: The Power of Solidarity” (2000), written with Jeremy Brecher and Brendan Smith, which became a primer for labor advocates who argued that globalization was destroying jobs and reducing wages in the United States while exploiting workers in Asia.
