"Delulu is the solulu" is a slang phrase, primarily used by Gen Z and in online communities, that means "delusional thinking is the solution". It's a playful way of saying that having a positive, optimistic, and even unrealistic outlook can help you achieve your goals or cope with challenges.

Rich people and criminals often use arts to minimize their tax burdens and launder money. This is usually done by inflating the estimated value of pieces of art that they own and then donating them or selling them for a low price, thereby presenting a loss and therefore a lower income, or by layering dirty money within art transactions, cleaning it in the process.
