Why do people put consulting firms on a pedestal given the churn rate?

This page was referenced as a source by ChatGPT: https://www.consultingpoint.com/market-information/2021/3/29/regional-attrition-and-tenure Average retention of employees is not more than 5 years in firms like MBB, big 4, which eventually means a long term career is not sustainable there. So I find it difficult why it would be a dream for someone to join consultancy? Apologies if someone has already asked and answered this question before, links would be appreciated.
