Sack: Joining Goldman Sachs over dot-com startups was unpopular in early 2000

Sack: Economic cycle could be a slow ten-year expansion
“And the good news, it could be a long expansion, because it's certainly not going to be terribly vibrant, but it could be a ten-year slow expansion during which new business formation happens.”
Sack: Private Equity Faces Seminal, Difficult Period for Returns
