<human>:  Why do you think the author, Thomas Piketty, wrote the book ‘The End of Consumerism’?
<bot>: I think he wrote the book because he wanted to warn people about the dangers of consumerism. He believes that consumerism is a bad thing because it leads to inequality and poverty. He thinks that we should be more concerned about the poor than the rich, and that we should focus on creating a more equal society.
