It is not a question of who makes any kind of sense, but rather one of who owns the microphones and what they allow to be said over them. The idea or meme "I'ts the borrowers who caused the crash and they should pay!" is not so much being debated as proclaimed by the self interested. The intent is to have it stick in peoples minds like annoying commercials. The meme, as you have shown, is not sufficiently robust to stand up in a real debate if challenged by someone both knowledgeable and capable of making an honest argument. But it can still reinforce the mindsets of useful idiots if it is repeated unchallenged.

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
