If I may make the counter argument here, nobody except perhaps the odds makers in the bay area, are going to note or care if Sequoia Ventures loses all of its investment in Uber, or if Menlo does, or if KP does. It will show up on CNBC as "Well its been a bad year for Venture Capital firms, probably not going to host lavish parties..." but for most people who don't work at a company that goes 'poof' because it ran out of money and couldn't raise more, its really a non issue.

For bubbles to really be bubbles they need broad participation, and VC funding really is limited in how many people can participate.
