The main reason Gillian Tett gives for the collapse of the financial services industry in the years before the 2008 crash is insular thinking.
This is the possibility that investors and other monetary experts were too centered around their thin advantages and not giving sufficient consideration to the more extensive results of their choices, both financial and social.
Tett contends that this prompted a culture of over-the-top gamble-taking, where choices were made with little thought for their drawn-out suggestions. She further contends that this separate reasoning was intensified by an absence of thoughtfulness regarding society and to the human impacts of monetary choices.
This absence of comprehension of the human component in finance implied that financiers didn't know about the likely outcomes of their activities, prompting the development of impractical obligations and eventually the accident.
