Amazon makes a new push into health care

AS BIG TECH firms face a brutal slow-down the hunt is on for new areas of expansion. Amazon, which is now America’s second-biggest business by revenue, is a case in point. In the final quarter of 2022 its sales are expected to expand by just 6.7% year-on-year. On November 17th Andy Jassy, its chief executive, confirmed that the firm had begun laying off workers and would fire more next year. He said it was the hardest decision he had made since becoming boss. But he also noted that “big opportunities” lie ahead. One is the largest, most lucrative and hellishly difficult business in America: health care.
