The Late Show with Stephen Colbert's May 21, 2022 Crypto Celebs Silent As Market Melts Down | Billionaires Get Ready To Trip At Davos cites Business Insider's August 27, 2020 (updated) Davos 2021 is postponed — here's what you need to know about the invitation-only conference that brings billionaires together with business and political leaders at a Swiss ski resort (which in turn cites CBS News' January 19, 2018 What is Davos?) and Entrepreneur's May 16, 2022 Who Gets to Attend Davos? Everything You Need to Know About the Notoriously Difficult-to-Get-Into Conference
The Business Insider quote that Colbert highlights is:
...conference that brings billionaires together with business and political leaders at a Swiss ski resort...
and that of Entrepreneurs':
Participants address critical concerns including wealth management, climate change...and...more.
Question: What fraction of Davos participants are billionaires (and not corporations or political leaders) and who decides which ones can go?
I understand there could be some overlap; I'm only asking about participants who's only qualifications are the amount of money they have and control.
From Wikipedia's World Economic Forum; Annual meeting in Davos:
At the 2018 annual meeting, more than 3,000 participants from nearly 110 countries participated in over 400 sessions. Participation included more than 340 public figures, including more than 70 heads of state and government and 45 heads of international organizations; 230 media representatives and almost 40 cultural leaders were represented.
