For example, harmonizing insolvency regimes across the continent and reducing tax incentives that favor debt over equity, while entirely logical, strike at the heart of member states' remaining sovereignty, and thus will be extremely difficult to push forward. Some of the other ideas that Hill has floated, such as relaxing the capital standards for long-term investments, run counter to the EU solvency standards for insurers and pension funds that will be implemented next year.
事实上，尽管希尔的初始日程相当温和，绝不会造成任何伤害（并且应该尽快实施），但任何此后的重大措施将面临严重挑战。比如，协调整个欧洲大陆的清算机制并降低有利于债务而不利于股权的税收融资尽管十分符合逻辑，但也影响到成员国剩余主权的核心，因此极难推行。希尔提出的其他一些想法，比如放松长期投资的资本要求，与将在明年实施的欧盟保险商和养老基金偿债能力要求相违背。
