If social capital is expecting to benefit from a share of the human capital of others, there may not be enough “others” in future generations to contribute to the well being of the current generation. It is interesting to speculate about how much guaranteed income the economy can be expected to support at any given time and for what categories of people.
1.8 billion people who have access to a water source within 1 kilometre, but not in their house or yard, consume around 20 litres per day. In the United Kingdom the average person uses more than 50 litres of water a day flushing toilets (where average daily water usage is about 150 liters a day. The highest average water use in the world is in the US, at 600 liters day.)
4. Calculate how much passive income you need. It's important to have a passive-income goal — otherwise, it's very easy to lose motivation. A good goal is to try to generate enough passive income to cover basic living expenses such as food, shelter, transportation, and clothing. If your annual expense number is $30,000, divide that figure by your expected rate of return to see how much capital you need to save. Unfortunately, you've got to then multiply the capital amount by 1.25 to 1.5 to account for taxes.

IDA has invested more than $2 billion since 1991 to address the country’s infrastructure gap, partly through the Road Sector Development Program (RSDP). IDA helped build capacity and establish a dedicated road fund for financing maintenance. Working in partnership with other donors, including the European Commission, Germany, Japan, Nordic countries and the United Kingdom, IDA helped increase both the size and quality of Ethiopia’s road network from under 20,000 km in 1991 to over 100,000 km in 2015. Under the CPF, the World Bank continues supporting improvements in transport infrastructure and road connectivity to reduce travel times and improve connectivity between markets and secondary cities.
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.
