I do think that there are some firms, who cater to mostly very wealthy clients, who can consistently beat the market, or at least have a good chance of finding some niche or anomaly every few years for a huge jackpot such that their overall average is higher than the indexes.

The problem is that most of us won't have access to these people.

Instead, our professional is going to be the typical financial planner who has far less of an understanding of math than even the typical CS / engineer grad, and is basically a commissioned sales person who will take 5% off the top, plus another 2% a year - all for basically investing it in the same index funds you can now buy yourself with a Schwab or Vanguard account.
