I trust the physical impossibility of tracking cash over the hypothetical enforcement of legislation any day. Why risk it? How many employers have used data on candidate salaries in violation of the law in California? How would we ever know? There are many benefits of using cash: it's very secure, as long as I'm sensible. It's anonymous. It costs those that I do business with less to maintain (Visa charges 2%. 2 percent! of revenue!). People who I tip like me more because I tip in cash. Businesses I do business with like me more because I give them cash. Not to mention, I can do business with anyone I want if I deal with cash -- not so with electronic services. Look to the case of Germany for why cash is so important.
