India is one of the largest centres for polishing diamonds and gems and manufacturing jewellery; it is also one of the two largest consumers of gold.[183][184] After crude oil and petroleum products, the export and import of gold, precious metals, precious stones, gems and jewellery accounts for the largest portion of India's global trade. The industry contributes about 7% of India's GDP, employs millions, and is a major source of its foreign-exchange earnings.[185] The gems and jewellery industry, in 2013, created ₹251,000 crore (US$35 billion) in economic output on value-added basis. It is growing sector of Indian economy, and A.T. Kearney projects it to grow to ₹500,000 crore (US$70 billion) by 2018.[186]
If you ask most people, social capital may not feel as strong or secure as it once did. Many people, especially younger people, do not expect to see a positive return on their Social Security contributions. Some do not expect to see anything at all from the Social Security Administration. The demographics of the system have changed from a past where many workers supported few retirees to a near future where existing workers cannot support the many retirees.
The original version of Barbara Winter’s book, Making a Living Without a Job, came out in 1993, and in it, she recommended creating multiple "profit centers," as opposed to building a single income stream. Over ten years later,  Robert Allen, the real estate entrepreneur, also wrote a couple books promoting the idea of multiple streams of income. Back then, building more than one source of income was difficult, time-consuming, and expensive. Fortunately, things have changed today. The Internet has made it easier, faster, and more affordable to generate multiple income streams.

The growth in the IT sector is attributed to increased specialisation, and an availability of a large pool of low-cost, highly skilled, fluent English-speaking workers – matched by increased demand from foreign consumers interested in India's service exports, or looking to outsource their operations. The share of the Indian IT industry in the country's GDP increased from 4.8% in 2005–06 to 7% in 2008.[214] In 2009, seven Indian firms were listed among the top 15 technology outsourcing companies in the world.[215]

Maybe such a business is owning a McDonald’s franchise or something. If one has the capital (Feasibility Score 2), then the returns might be good (Return Score 6). But the Risk Score is probably under a 5, b/c how many times have we seen franchise chains come and go? Like, what happened to Quiznos and Jamba Juice? A McDonald’s franchise was $500,000… probably much more now?

Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
