I've studied LC. I have doubts about their grading of loans, and they acknowledged to me that they had no way to model a serious downturn in the economy. The weakness is that they need to produce revenue growth, and ultimately they are in a conflict of interest situation. They might make weaker loans. Packaging of loans is what Wall Street did. Everyone knows S&P and Moodys mis-graded debt. I think you should offer some proof of the mischief that LC has perpetrated on the world. It's not inherently 'bad' just as CF is not inherently bad. It is an alternative to making loans through banks.
Anyone who looks at the collapse of 2008, the lending standards of Countrywide, is going to have a hard time making peer to peer look hopelessly corrupt.
I don't know who you like. Chase? Citi? Wells? How much info should be we get on derivatives? Life insurance companies are increasingly demanding the right to make riskier investments. Peer to peer could be much cleaner if you can keep the gatekeeper honest. LC takes 1% off the top, many mutual funds have much higher fee structures for income investments.
There's no way this is not, in part, the future. In a town full of payday and title loan shops, LC doesn't seem like it is anywhere near that level of depravity.
