I don't wish to be tiresome by commenting on grammar and usage, though the opportunities are increasing exponentially, but this one is irresistible:
"Today's tech and telecom companies build products that require less American workers, less middle-income workers, and less workers overall. "
"Less" is used for quantities of things that can't be counted individually, as in "less water", "less compassion". The correct usage would be "fewer", as workers can be individually counted.
In this case, however, one might argue that to the corporations workers are seen as a faceless mass without individual identity, so perhaps Mr. Buchheit is unintentionally accurate with his use of "less". Sad.
