It all depends on the actual numbers. Consider this simplified example: If you are offered a deal that requires you to lay down 10 billion today and it has a 5% chance to pay out 150 billion tomorrow, your accountants will tell you not to take this deal because your expected return is -2.5 billion. But if you can offset 3 billion in cost to the tax payer, your expected return suddenly becomes $500 million, making it a good deal that you should take every time.
