Net worth in the context of "Haig–Simons income"

Wealth is the abundance of valuable financial assets or physical possessions which can be converted into a form that can be used for transactions. This includes the core meaning as held in the originating Old English word weal, which is from an Indo-European word stem. The modern concept of wealth is of significance in all areas of economics, and clearly so for growth economics and development economics, yet the meaning of wealth is context-dependent. A person possessing a substantial net worth is known as wealthy. Net worth is defined as the current value of one's assets less liabilities (excluding the principal in trust accounts).

At the most general level, economists may define wealth as "the total of anything of value" that captures both the subjective nature of the idea and the idea that it is not a fixed or static concept. Various definitions and concepts of wealth have been asserted by various people in different contexts. Defining wealth can be a normative process with various ethical implications, since often wealth maximization is seen as a goal or is thought to be a normative principle of its own. A community, region or country that possesses an abundance of such possessions or resources to the benefit of the common good is known as wealthy.

In economics, the profit motive is the motivation of firms that operate so as to maximize their profits. Mainstream microeconomic theory posits that the ultimate goal of a business is "to make money" - not in the sense of increasing the firm's stock of means of payment (which is usually kept to a necessary minimum because means of payment incur costs, i.e. interest or foregone yields), but in the sense of "increasing net worth". Stated differently, the reason for a business's existence is to turn a profit.The profit motive is a key tenet of rational choice theory, or the theory that economic agents tend to pursue what is in their own best interests. In accordance with this doctrine, businesses seek to benefit themselves and/or their shareholders by maximizing profits.

As it extends beyond economics into ideology, the profit motive has been a major matter of contention.

In common law, an estate is a living or deceased person's net worth. It is the sum of a person's assets; their legal rights, interests, and entitlements to property of any kind, minus all of their liabilities at a given time. The issue is of special legal significance on a question of bankruptcy and death of the person. (See inheritance.)

Depending on the particular context, the term is also used in reference to an estate in land or of a particular kind of property (such as real estate or personal estate). The term is also used to refer to the sum of a person's assets only.

George Soros (born György Schwartz; August 12, 1930) is a Hungarian-American investor and philanthropist. As of May 2025, he has a net worth of US$7.2 billion, having donated more than $32 billion to the Open Society Foundations, of which $15 billion has already been distributed, representing 64% of his original fortune. In 2020, Forbes called Soros the "most generous giver" in terms of percentage of net worth.

Born in Budapest to a non-observant Jewish family, Soros survived the Nazi occupation of Hungary and moved to the United Kingdom in 1947. He studied at the London School of Economics and was awarded a BSc in philosophy in 1951, and then a Master of Science degree, also in philosophy, in 1954. Soros started his career working in British and American merchant banks, before setting up his first hedge fund, Double Eagle, in 1969. Profits from this fund provided the seed money for Soros Fund Management, his second hedge fund, in 1970. Double Eagle was renamed Quantum Fund and was the principal firm Soros advised. At its founding, Quantum Fund had $12 million in assets under management, and as of 2011 it had $25 billion, the majority of Soros's overall net worth.

A billionaire is a person whose net worth is at least one billion units of a given currency, typically USD. It is a sub-category of the concept of the ultra high-net-worth individual. The American business magazine Forbes produces a global list of known U.S. dollar billionaires every year and updates an internet version of this list in real time. The American oil magnate John D. Rockefeller became the world's first confirmed billionaire in 1916.

Nineteen individuals had attained the status of centibillionaires, each with a net worth of at least $100 billion, as of October 2025. As of March 2025, there are 3028 billionaires worldwide, with a combined wealth of over $16.1 trillion, up nearly $2 trillion over 2024.

A millionaire is an individual whose net worth or wealth is equal to or exceeds one million units of currency. Depending on the currency, a certain level of prestige is associated with being a millionaire.Many national currencies have, or have had at various times, a low unit value, in many cases due to past inflation. It is much easier and less significant to be a millionaire in those currencies, thus a millionaire in the local currency of Hong Kong or Taiwan, for example, may be merely of average wealth, or perhaps less wealthy than average. A millionaire in Zimbabwe in 2007 could have been extremely poor. Because of this, the term 'millionaire' generally refers to those whose assets total at least one million units of a high-value currency, such as the United States dollar, euro, or pound sterling.

At the end of 2011, there were around 5.1 million high-net-worth individuals (HNWIs) in the United States, while at the same time there were 11 million millionaires in a total of 3.5 million millionaire households, including those 5.1 million HNWIs. In countries that use the short scale number naming system, a billionaire is someone who has at least a thousand times a million dollars, euros or pounds.

The World's Billionaires is an annual ranking of people who are billionaires, i.e., they are considered to have a net worth of US$1 billion or more, by the American business magazine Forbes. The list was first published in March 1987. The total net worth of each individual on the list is estimated and is cited in United States dollars, based on their documented assets and accounting for debt and other factors. Royalty and dictators whose wealth comes from their positions are excluded from these lists. This ranking is an index of the wealthiest documented individuals, excluding any ranking of those with wealth that is not able to be completely ascertained.

In 2018, Amazon founder Jeff Bezos was ranked at the top for the first time and became the first centibillionaire included in the ranking, surpassing Microsoft founder Bill Gates, who had topped the list 18 of the previous 24 years. In 2022, after topping the list for four years, Bezos was surpassed by Elon Musk. In 2023, Musk was in turn surpassed by French businessman Bernard Arnault, after topping the list for just a year. Arnault became the first French person to top the list. In 2025, Musk once again became the wealthiest man in the list after surpassing Arnault.
