Three engineers have the same amount of schooling and work experience, but earn different wages. One is a computer engineer who designs and tests new computers for an annual wage of $54,000 per year. Another is a chemical engineer who works in a nuclear lab and performs experiments on radioactive materials for an annual wage of $80,000 per year. The third is a civil engineer who performs daily inspections of cables on a suspension bridge for an annual wage of $91,000 per year.
