The definition of Walth is anything but standard. And any definition which includes assets with associated liabilities and/or debt greater than the value of the asset is quite useless. Here's some of the definitions found at various universities:
While the dictionary definition of wealth is connected with affluence—having an abundance of money, Schuchardt says wealth is “about having enough money to be financially secure. The concept of financial security means you are first, financially independent, or out on your own; then financially stable, or able to meet day-to-day expenses; and finally, able to save, invest, and control debt in order to reach future goals that take money to buy, such as a home, a college education and a comfortable retirement.” Schuchardt, a former senior fellow with the National Endowment for Financial Education, suggests these simple tactics:

Our definition of wealth includes business assets and non-residential properties. We are interested in looking at the assets of these households that can be expected to generate a stream of income that can be used to finance consumption during retirement.

Program, we assume that utility is a function of wealth, that utility always increases with wealth, but that the marginal utility of wealth decreases as wealth increases. The goal of the consumer is to maximize
expected lifetime utility. Utility is assumed to be a function of wealth. The definition of wealth can be a sticky issue, but initially we can think of a retired person whose only source of income is perfectly liquid,
perfectly safe financial assets
.
Relative Risk Aversion
Utility functions can be characterized in terms of relative risk aversion, which is the same as the wealth elasticity of the marginal utility of wealth (Blume & Friend 1975). Relative risk aversion can be plausibly
assumed to be constant for any person over usual ranges of wealth. Kimball (1988) has provided a nice intuitive illustration of the concept of relative risk aversion, appropriate for utility functions with constant
relative risk aversion.

A. Definitions of wealth, expected returns and unexpected capital gains:
Given the definition of wealth in (1), the expected total return can be written in terms of yield and expected capital gain:

You're free to state your preferred definition or if you don't like any possible existing static definitions, that's fine too. Lots of good people make up definitions in mid sentence. I find it less work to use the definitions from U Mich, they serve well when working in financial careers such as mine. I can understand how someone else could define wealth as anything they want just to win an argument. I find it too much work to switch definitions when going from work to worship or home.
