Income and assets are mostly matched.

For example.

A person around 35 years old with assets exceeding 100 million.

Such a person, unless they are a second-generation rich, would definitely have an annual income of over 10 million; it is unlikely that they only earn 1 million or 2 million.

Because, without family support, to accumulate assets over 100 million by around 35 years old, they absolutely wouldn't be earning just 1 million or 2 million a year; they would definitely be in the super high-income group.

A person around 35 years old with assets over 100 million and an annual income of 1 million or 2 million is either a second-generation rich or a fraud.
