White collar crimes (like this should be) are all about making value calculations. Take the famous Ford Pinto memo. They decided the risk to their customers' lives was smaller (in terms of pure dollar amount, after potential litigation) than fixing the gas tank issue. If you penalize reckless security practices that lead to data breaches companies will be far more inclined to look after their customers. We already issue fines like this with COPPA, so it's not a new concept.
Street crimes have a far different cause and should be treated differently. I'm surprised I even have to type that, it seems obvious.
