Look at a job description that a company owner passed along to New York Times columnist Thomas Friedman in a piece he wrote about the paucity of trained American workers. The company owner was looking for a welder and was complaining about the quality of some who had applied:
"They could make beautiful welds," she said, "but they did not understand metallurgy, modern cleaning and brushing techniques" and how different metals and gases, pressures and temperatures had to be combined. Moreover, in small manufacturing businesses like hers, explained [Traci] Tapani, "unlike a Chinese firm that does high-volume, low-tech jobs, we do a lot of low-volume, high-tech jobs, and each one has its own design drawings. So a welder has to be able to read and understand five different design drawings in a single day ... I can't think of any job in my sheet metal fabrication company where math is not important. If you work in a manufacturing facility, you use math every day; you need to compute angles and understand what happens to a piece of metal when it's bent to a certain angle."
