When we worry about who might be spying .on our private lives, we usually, think about the Federal agents. But the private sector outdoes the government every time. It’s Linda Tripp, not the FBI, who is facing charges under Maryland’s laws against secret telephone taping. It’s our banks, not the Internal Revenue Service (IRS), that pass our private financial data to telemarketing firms.
Consumer activists are pressing Congress for better privacy laws without much result so far. The legislators lean toward letting business people track our financial habits virtually at will.
As an example of what’s going on, consider U.S. Bancorp, which was recently sued for deceptive practices by the state of Minnesota. According to the lawsuit, the bank supplied a telemarketer called MemberWorks with sensitive customer data such as names, phone numbers, bank-account and credit-card numbers, Social Security numbers, account balances and credit limits.
A. is mainly carried out by means of secret taping
B. has been intensified with the help of the IRS
C. is practiced exclusively by the FBI
