To these human costs can be added the massive economic waste associated with the water and sanitation deficit.… The costs associated with health spending, productivity losses and labour diversions … are greatest in some of the poorest countries. Sub-Saharan Africa loses about 5% of GDP, or some $28.4 billion annually, a figure that exceeds total aid flows and debt relief to the region in 2003.Source 10
Has this thought ever struck you mind as what if your boss fired you overnight, what your course of action would be? I guess the answer is NOTHING! You have no monthly pay checks coming in, how are you going to put roof above your family’s head? How are you going to manage the bills payment? What would you feed to your family? An answer to all this lies in darkness…complete darkness in that situation. But I have answer to this question, because I am my own boss managing multiple things and earning from all of them at a time, losing one would not be that big deal to me.
In the runup to the Second World War, the United States had suffered through the Great Depression following the Wall Street Crash of 1929. Roosevelt's election at the end of 1932 was based on a commitment to reform the economy and society through a "New Deal" program. The first indication of a commitment to government guarantees of social and economic rights came in an address to the Commonwealth Club on September 23, 1932 during his campaign. The speech was written with Adolf A. Berle, a professor of corporate law at Columbia University. A key passage read:
Let us start by creating a corpus to invest your money. Let us say you are 25 years of age and earning Rs.75,000 per month after completing your MBA. You can save Rs.10,000 per month in an equity fund as you have other commitments with the rest of the money. But starting off with Rs.10,000 per month in an equity fund SIP is not bad enough. Here is why.

The goal of creating multiple income streams should be to maximize your potential in each category available to you.  If you are just starting out, it really isn’t reasonable to expect you to generate tons of rental income.  However, if you start maximizing your income generating potential through your primary salary, you will find yourself having excess income that you can reinvest to generate additional income streams and earn more money.

Based on my initial experience of passive income, I feel real that real estate is best vehicle to build long-term investment. I live in Los Angeles and was able to cash flow my first rental property. What are you thoughts about starting out to build a passive income portfolio? I have utilized Lendingclub, online savings, and a small dividend/bond portfolio.
This is an interesting take and good advice for those who probably do not need to ever worry about becoming destitute. I’m sorry but too many of your options including your own list of income require quite a bit of initial investment/capital and these suggestions are useless to those living paycheck to paycheck. I’d like to see the average low to middle income household purchase additional property for rental, invest in their portfolio (if they can even start one), or even afford to have a vehicle or room to rent. Far too first world of a solution for the general public.

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.
