Hoisted from comments: Daniel Davies gives the big important argument for investing in private equity:
If you believe that you have the self-discipline to "buy and hold" a portfolio of "mid cap value stocks" for ten years, despite the fact that during that time many of them will deliver heartbreakingly awful newsflow and earnings, then go for it.
The private equity industry.
PS: The evidence of the entire history of investing is that you don't.
