B.C. could do with more health workers, engineers, plumbers and even coal miners. But do we really need more teachers, journalists and carbon-loathing eco-activists? No, we're way oversupplied with them already.
Another tactic used in the article is loaded language. He uses a very specific and emotional word when he talks about young people who are who are "either unemployed or underemployed ... and have been badly scarred by the experience"
