Y'all don't understand how the extremely wealthy operate.
For one of us to buy that banana it would cost about .35 cents. Duct tape has to be bought in a roll for a couple bucks. Total investment about $3-$4. (I haven't bought duct tape in awhile so my price may be way off)
Art is in the eye of the beholder. This guy worth billions, pays millions to eat the banana. Gets a ton of social media thumbs up and moves along with his life as a special person. The likes are what he lives for.
Dropping 6 million for him is like us buying a fast-food burger to eat. It's nothing.
