sentences:  Some economists such as Paul Krugman hold that economies of scale in banks and in other businesses are worth preserving, so long as they are well regulated in proportion to their economic clout, and therefore that "too big to fail" status can be acceptable.The global economic system must also deal with sovereign states being too big to fail.Opponents believe that one of the problems that arises is moral hazard whereby a company that benefits from these protective policies will seek to profit by it, deliberately taking positions (see asset allocation) that are high-risk high-return, as they are able to leverage these risks based on the policy preference they receive.
