I don’t know. I kindof suspect that:

• The billionaires may somewhat believe their own propaganda and maybe the climate chang denying billionaires may outnumber the ones who are more in touch with reality.
• The machines that capitalism has built to maintain and intensify wealth concentration may well have escaped the control of their creators. Corporations have wills of their own distinct from that of the people nominally “in charge” like the C-level leaders and board and shareholders.
• Climate change itself may have already passed a point of no return or if it hasn’t, it likely will before even the most powerful manage to redirect the momentum of the system in a different direction.
