The Wall Street Journal provides yet another indicator of strained consumer budgets. More and more are having trouble paying their utility bills, precisely when the service providers are getting tougher about collections:

Utilities are becoming more aggressive about collecting money from delinquent customers, leading to a surge in service shutdowns just as economic woes are pushing up the number of households falling behind on bills.

In Pennsylvania, PPL Corp. increased shutoffs by 78% in the first three quarters of the year compared with the same period a year earlier.

State regulators say they have noticed that power shutoffs have moved up the economic chain. “We’re seeing an uptick in middle-class people who have never been in this situation before,” said Eric Hartsfield, director of the customer-service division of the New Jersey Board of Public Utilities.

New Jersey’s biggest utility company, Public Service Enterprise Group Inc., said it saw a 10% increase compared with the year earlier in uncollectible natural-gas accounts, and slightly less on the electric side…
