Stocks (shares) paying dividends are typically a reliable source of income but they have higher risk of capital losses than cash and bonds. So, it’s wise not to chase yield indiscriminately.  The 10 highest yielding stocks on the ASX 200 (the 200 largest companies in Australia) are shown in the table below.  But their share price performance on average over the last year has been underwhelming, as shown in the far right column:
The key liability that remains, as human capital dwindles, should be funding one’s retirement income. Given the blended retirement pattern discussed in this column last March, we can expect that some retirees will start spending their financial capital and others will keep building it, at least for a while. Do you know how your investor clients plan to blend remaining human capital with their (hopefully growing) financial capital and social capital to meet their remaining (and, one hopes, limited to retirement income) liabilities?

In federal legislation, the key planks for the right to a useful and remunerative job included the National Labor Relations Act of 1935 and the Fair Labor Standards Act of 1938. After the war was the Employment Act of 1946, which created an objective for the government to eliminate unemployment; and the Civil Rights Act of 1964, which prohibited unjustified discrimination in the workplace and in access to public and private services. They remained some of the key elements of labor law. The rights to food and fair agricultural wages was assured by numerous Acts on agriculture in the United States and by the Food Stamp Act of 1964. The right to freedom from unfair competition was primarily seen to be achievable through the Federal Trade Commission and the Department of Justice's enforcement of both the Sherman Act of 1890 and the Clayton Act of 1914, with some minor later amendments. The most significant program of change occurred through Lyndon B. Johnson's Great Society. The right to housing was developed through a policy of subsidies and government building under the Housing and Urban Development Act of 1965. The right to health care was partly improved by the Social Security Act of 1965 and more recently the Patient Protection and Affordable Care Act of 2010. The Social Security Act of 1935 had laid the groundwork for protection from fear of old age, sickness, accident and unemployment. The right to a decent education was shaped heavily by Supreme Court jurisprudence and the administration of education was left to the states, particularly with Brown v. Board of Education. A legislative framework developed through the Elementary and Secondary Education Act of 1965 and in higher education a measure of improvement began with federal assistance and regulation in the Higher Education Act of 1965.
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.
