As with so much in life too much of anything is bad. Obsession for dealing with inequality without grasping the potential of new technology and people with skills, has hurt both China and India, with both moving to correct this in the last 20 years. Allowing too much inequality disturbs the balance in society damaging democratic processes and creating new dangers for democratic processes. 

Today Piketty, and other Western and Asian leaders are presenting the argument for fairer societies principally because this is the only way to generate the kind of cycle for growth seen after the second  world war in the 1940's, 1950's and 1960's  following FDR and Truman, De Gaulle and Adenauer. At some point the curve for growth simply drops with extreme disparities in society- something that happened with disastrous consequences in the history of China and India in the 1500's and the long descent into colonial or semi-colonial rule. That pattern is documented in Adam Smith's Wealth of Nations. And it is a drop no nation or society would want to repeat because of the immense suffering, and the decline of Asian societies in a social and cultural sense, leading to a closed outlook to science in general and knowledge accumulation behaviours based on scientific observation of Nature over the course of the 17th to 19th century. 

Some traces of this in the early stages are evident in the US and Europe which is why all well meaning people and people of goodwill for their countries seek a way out of this endless fracturing, the rural-urban divide, the society blind and morally neutral views of tech, and the starving of resources which benefit the broad segments of society for infrastructure, health and education through the misallocation of resources to other places.

In the long run what is important is not the long theories which can fail, but to "Just Do," follow good common sense, do the right thing as Modi has done for women in essentials such as water, toilets, cooking gas, digital bank accounts, dignity, safety, access to education. And what Xi is attempting to do for Common Prosperity in China. And what Biden and Scholz are setting out to do in the US and Germany.
