Despite being bombarded daily by news about European sovereign debt issues, the oil leak in the Gulf of Mexico and the U.S. federal deficit, the vast majority of consumers say these and other crises have had little impact on their current spending habits, according to the monthly RBC Consumer Outlook. More than three-in-four Americans (80 percent) say that the European debt crisis has had no effect on their spending habits, and 72 percent say that the Gulf oil spill will result in no change. Other concerns, such as the federal budget deficit, stock market volatility and continued high unemployment, also have had little impact.
