5. Banks use databases to identify profitable and unprofitable customers. Bankers say they lose money on customers who typically keep less than $1,000 in their checking and savings accounts and frequently call or visit the bank. Profitable customers keep several thousand dollars in their accounts and seldom visit a teller or call the bank. To turn unprofitable customers into profitable ones, banks have assessed fees on almost 300 services, including using a bank teller, although many of the fees are waived for customers who maintain high account balances. Bankers justify the fees by saying they’re in business to earn a profit. Discuss whether banks are justified in treating profitable and unprofitable customers differently. Defend your answers.
