It’s a desperate attempt by people who understand that identifying huge problems in the easy part. So much of life is just people thinking that by identifying the problem they’re 99% of the way to fixing it.
But apply this to something you understand in detail, unlike a whole society. “That guy has a bad heart, better fix it!” That’s something that doesn’t need to be said, never mind repeated like a solution to a hard problem.
“Come up with something new maybe?” Is a trite attempt at belittling a conversation that is seeking knowledge and frankly just annoying.
