Rising prices taking a bite out of American wallets caused consumer sentiment to drop to a 10-year low in November, a sign inflation is increasingly a political liability for President Joe Biden. While the world’s largest economy has bounced back strongly from the Covid-19 pandemic impact, global shortages of key components and supply chain snarls have added to a US worker shortage, raising costs and pushing prices higher. Following a government data report Wednesday showing consumer price inflation jumped to a 30-year high of 6.2 percent in October, a survey released Friday with the sharp drop in sentiment came as another blow, although economists do not expect shoppers to pull back on spending. The University of Michigan said its preliminary sentiment index dropped to 66.8 this month, a 6.8 percent decline. Survey chief economist Richard Curtin said one in four families suffered eroding living standards but lower income families were feeling the most pain. Biden on Wednesday pledged to make putting a lid on inflation was a “top priority,” but Curtin attributed the dismal sentiment reading to “the growing belief among consumers that no effective policies have yet been developed to reduce the damage from surging inflation.”
