It also shows clearly why the median and the mean of the asymmetrical log-normal, even more so for a power law, differ and represent threshold conditions. One does not have to get into the mathematics to see that averages in an asymmetrical distribution do not convey the same degree of the “typical investor behavior” that they convey in a symmetrical distribution. How do you optimize your practice for the average investor if your own investor income and wealth data follow such an asymmetrical distribution?

Start an affiliate marketing website: This passive income model works for individuals who already own a bog or website. Here, your business goal is to contact companies and offer to tout their products and services, usually for a fee or a commission, based on the number of page views you get. Studies show that more people spend time online and less watching TV or reading the newspaper. Take advantage of that leverage and earn income from the tens of thousands of companies who want to reach an audience - maybe your audience. Either reach out to companies directly or go through a site like ClickBank, which offers affiliate marketing opportunities.

As a private lender, you can lend to anyone in your social circle. For example, many home rehabbers need access to a source of capital they can tap into very quickly in order to fund the initial purchase of their properties. You can partner with a rehabber who uses your capital for a short-term in exchange for an interest rate that is mutually agreed upon.
The five-year plans, especially in the pre-liberalisation era, attempted to reduce regional disparities by encouraging industrial development in the interior regions and distributing industries across states. The results have been discouraging as these measures increased inefficiency and hampered effective industrial growth.[397] The more advanced states have been better placed to benefit from liberalisation, with well-developed infrastructure and an educated and skilled workforce, which attract the manufacturing and service sectors. Governments of less-advanced states have tried to reduce disparities by offering tax holidays and cheap land, and focused on sectors like tourism which can develop faster than other sectors.[398][399] India's income Gini coefficient is 33.9, according to the United Nations Development Program (UNDP), indicating overall income distribution to be more uniform than East Asia, Latin America and Africa.[10]
Unemployment in India is characterised by chronic (disguised) unemployment. Government schemes that target eradication of both poverty and unemployment – which in recent decades has sent millions of poor and unskilled people into urban areas in search of livelihoods – attempt to solve the problem by providing financial assistance for starting businesses, honing skills, setting up public sector enterprises, reservations in governments, etc. The decline in organised employment, due to the decreased role of the public sector after liberalisation, has further underlined the need for focusing on better education and created political pressure for further reforms.[354][355] India's labour regulations are heavy, even by developing country standards, and analysts have urged the government to abolish or modify them in order to make the environment more conducive for employment generation.[356][357] The 11th five-year plan has also identified the need for a congenial environment to be created for employment generation, by reducing the number of permissions and other bureaucratic clearances required.[358] Inequalities and inadequacies in the education system have been identified as an obstacle, which prevents the benefits of increased employment opportunities from reaching all sectors of society.[359]
Now, all that said, if capital (savings) grows faster than the growth of the economy, those with savings will see their wealth grow at a faster rate than those who rely on the growth of their income. While this is not an extension of Piketty's argument (you can't take an idea that applies to a population and a whole economy and boil it down to the individual like this), it's not an unreasonable conclusion to take and apply to your own life. (Piketty does talk about this on an individual level, but says it's more impactful for billionaires vs. millionaires – though we have limited data into individuals)
While it is important to find something that you love to do and turn it into a money making business, you do have to be cognizant of the return as you pointed out. There are many opportunities that I found and tried out that at the time seemed great. But when I took a step back, I realized that I was working a lot for very little income whereas other things I love doing brought in much more money.

The average population of counties with per capita incomes above the state's was twice as high (921,098) as those with a per capita income below the state average (546,543). Even this difference is minuscule when population density is considered: Counties with a per capita income above that of the state were eight times as dense on average (1,540.2 persons per square mile) than those with per capita income below that of the state (192.1 persons per square mile).
Retirees are paying a high price as the world stimulates its way out of the GFC (Great Recession).  After a 30-year bull market to the lowest interest rates the world has ever seen, bonds have become highly priced and now don’t generate enough to meet income needs.  Just 5 years ago the average income from $100,000 invested in a 10 year Australian Government Bond (10yrs) was $5,600 p.a.  – now it’s less than half at $2,600 p.a.
