May 7 (Bloomberg) -- Goldman Sachs Group Inc. Chief Executive Officer Lloyd Blankfein said heâs confident European leaders will find a way out of the Greek debt crisis, and they need to bolster flagging investor confidence. âThe market needs to be calmed down,â Blankfein said in a Bloomberg Television interview today after the annual shareholder meeting in lower Manhattan. He compared the loss of confidence among investors to events in 2008, when credit markets froze. âWeâre dealing with sentiment,â he said. Blankfein said heâs âreasonably confidentâ that sovereign nations will get together to find a solution. http://www.bloomberg.com/apps/news?pid=20601087&sid=ayHh8yNjhE7Y&pos=3 Hum, what does he know we do not ?
