As I look at the world of investment options, I don’t see anything that perfectly fits this description. There are few things that come even close.

Thus, the concept will remain a dream.

You’re right that it’s not too hard to find a single investment that clears the 10% return threshold for some period of time. The challenge lies in creating that cash flow overall from your investable capital base on a consistent basis without the investor’s active involvement.

It’s also an asset allocation issue – you want some money allocated to safer or more liquid investments that may yield less than 10%, while other investments in the portfolio could be doing much more than 10%, but may have lumpy payout or require some setup time. Regardless, there is significant work to be done by the asset manager (if not the investor) to pick the right blend of assets to achieve the liquidity, safety, yield, and most importantly, lifestyle goals. Doing this well usually requires expertise, experience, and/or insider access to information or deal flow.
