You read a newspaper report that compares wages paid to employees at Starbucks in India and in the United Kingdom. At the​ time, 1 pound was equal to 87 rupees. The report says that Starbucks baristas in India are paid a mere 56 pence an​ hour, which is lower than the cheapest coffee that Starbucks sells in the United Kingdom. A friend of yours who read the report is appalled by this information and thinks that Starbucks ought to raise its salaries substantially in India. Is your friend necessarily​ correct?
