The Ng family, particularly brothers Robert and Philip Ng, have accumulated their wealth primarily through real estate ventures, as they are the sons of Singapore's real estate tycoon Ng Teng Fong. As of 2015, they have a combined net worth of approximately $11.5 billion. The family's wealth has been built on a strong foundation of property development and investment, which has been passed down and expanded by the current generation. Despite their significant wealth, the Ng brothers are known for not forgetting their roots. The family's success in wealth accumulation can also be attributed to effective wealth succession planning, ensuring that their amassed riches are preserved and managed across generations.
