Building (or rebuilding) things is a lucrative business to be in, especially in an era when lots of things are being blown up. Construction is a mega-industry with players raking in money for huge projects, from Bechtel's Big Dig to Kellogg Brown & Root's military bases in Iraq and Afghanistan. There are the small, mob-connected firms building at ground zero in New York, and even the bin Laden family, who largely built modern Saudia Arabia and Dubai. The companies who build dams, roads, schools, hospitals and military installations are a major economic and political force.
