the.com/ship of fools

means A group, organization, or society being led by incompetent or foolish people, careening toward disaster while no one competent is actually in charge.

from From an allegory going back to Plato, but the phrase itself was fixed by Sebastian Brant's 1494 German satire 'Das Narrenschiff' ('The Ship of Fools'), a bestselling poem that packed a boatload of fools — the vain, the greedy, the quarrelsome — onto one doomed vessel sailing nowhere in particular. Hieronymus Bosch painted his own version, and the image stuck because it's so useful: any committee, government, or crew of people confidently mismanaging a shared enterprise can be slotted straight into Brant's leaky boat.
