Tell me a few flaws of the Human Development Index from this passage

Context: The Human Development Index is a statistic composite index of life expectancy, education, and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI per capita is higher. It was developed by Pakistani economist Mahbub ul Haq and was further used to measure a country's development by the United Nations Development Programme 's Human Development Report Office.

The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index. While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development, while the HDI can be viewed as an index of 'potential' human development that could be achieved if there were no inequality."

The index is based on the human development approach, developed by Mahbub ul Haq, anchored in Amartya Sen's work on human capabilities, and often framed in terms of whether people are able to "be" and "do" desirable things in life. Examples include – being: well fed, sheltered, and healthy; doing: work, education, voting, participating in community life. The freedom of choice is central – someone choosing to be hungry is quite different from someone who is hungry because they cannot afford to buy food, or because the country is in a famine.

The index does not take into account several factors, such as the net wealth per capita or the relative quality of goods in a country. This situation tends to lower the ranking of some of the most developed countries, such as the G7 members and others.

Answer: Human Development Index has been revised in 2010 owing to a few limitations. HDI is believed to estimate the 'potential' human development that could be achieved if there were no inequality. The revised Inequality-adjusted Human Development Index (IHDI) is the actual level of human development (accounting for inequality). Secondly, HDI does not take into account several factors, such as the net wealth per capita or the relative quality of goods in a country. This situation tends to lower the ranking of some of the most developed countries, such as the G7 members and others.
