Do the "Useful Idiots" (look it up) who show up to do the billionaire's dirty work have any clue about what they are going to inflict on humanity?
Sure... Outlaw petrochemicals and take the clothes out of their closets, carpet from their floors, computers, any home entertainment device.... Heat, light, water and power.
Might as well do without food up on their high rises.
The clever ones have outthought their selves.
