The bubble is different this time. We may get a significant market correction, but the fact that money has been so cheap so long has a lot of balance sheets in good order. You also don't see P/Es in the 50/1 range as you did in 2000. Real estate will come down in markets where it is too high and retail space has probably peaked in a lot of places as retail brick and mortar consolidates. The Unicorn valuations are fiction no matter what happens in the market, but a correction will always accompany a flight to safety which means less money for risky start-ups.
