What is holding back investment (both in the United States and Europe) is lack of demand, not high taxes. Indeed, given that most investment is financed by debt, and that interest payments are tax-deductible, the level of corporate taxation has little effect on investment.
人们寄希望于更低的公司税能刺激投资。纯属无稽之谈。拖累投资（不管在美国还是在欧洲）的是缺少需求，而不是高税率。事实上，由于大部分投资通过债务融资，而利息偿付可以抵扣应税项目，因此公司税水平对投资几乎没有影响。
