No one wants to plan for a loss but it is always better to be prepared. US have recently seen a real estate meltdown that has caused the entire economies of the world to go into recession. So, it is very important to foresee such meltdowns and be prepared for losses. A second income source will ensure that you have enough rotational money to see you through losses.

I think more and more people are recognizing the advantages of having multiple sources of income, thanks to the Great Recession. It was a real wake-up call to many good workers who lost jobs not because of poor performance but due to restructuring and cost-savings. They never considered themselves to be vulnerable and they were. We do have multiple streams of income and a fully-funded emergency fund, which has helped my family weather the ups and down life has brought us, including job loss.
Business Income: Contrasting to the self-employed ones, the business owners do not do all the work on themselves. In fact they get things done by different set of people working for them and they run the business. They create a system which then functions smoothly even with minimal supervision. This calls for a much less risky position and allows you time to build more and more income sources for yourselves.
In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
