Better roads, ports, and even schools all contribute to a country’s competitiveness. No one attempts to use tariffs to balance those government-created differences in competitiveness, and there should be no such attempts if a cap-and-trade system is introduced.
看来，问题的解决远没有那么简单。在忙于推出关税之前，我们还应该知道，除了“总量管制和排放交易”系统，各国政府还有其他手段来提高本国的竞争力。完善本国的公路，港口，甚至是建立较好的学校都能增加一个国家的竞争力。我们不愿意看到政府用关税手段来影响产品的国际竞争力，这同样也违背了“总量管制和排放交易”系统的初衷。
