Detroit, an analogy

So lets say that you are an underwater homeowner. You cannot afford to pay your mortgage and your property is worth less than you paid for it. At the same time, you have four kids living at home and only one has a job which pays minimum wage. Would your solution be to buy a swimming pool? That is what Detroit is doing. Rather than pay their mortgage or even feed their kids, they are going to build a $450 million hockey arena.
