When you build a business, you're giving up active income (instead of working for pay, I'm volunteering at my own business) for future active and passive income. In the meanwhile, you'll need a way to pay for your expenses. It could be that you're building a business on the side, so you still have a day job, or you're living on those savings. Either way, you need a cushion.
In response, the Narasimha Rao government, including Finance Minister Manmohan Singh, initiated economic reforms in 1991. The reforms did away with the Licence Raj, reduced tariffs and interest rates and ended many public monopolies, allowing automatic approval of foreign direct investment in many sectors. Since then, the overall thrust of liberalisation has remained the same, although no government has tried to take on powerful lobbies such as trade unions and farmers, on contentious issues such as reforming labour laws and reducing agricultural subsidies. By the turn of the 21st century, India had progressed towards a free-market economy, with a substantial reduction in state control of the economy and increased financial liberalisation. This has been accompanied by increases in life expectancy, literacy rates and food security, although urban residents have benefited more than rural residents.
A normal distribution (bell curve) is the limit of what one would find by adding up the value of many independent quantities such as the height of people in a large group. A power law distribution is the limit of what one would find by multiplying the value of many independent quantities such as the relative size of forest fires over a large enough area and a long enough period of time.
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.

For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
