As much as Bernanke and others wish otherwise – and as much as bickering politicians seek to dump policy responsibilities on others – central banks do not have the proper tools to deal with the component of the unemployment crisis that results from insufficient investment in education, training, and physical capital. Likewise, they cannot fix debt overhangs, repair broken home financing, or address medium-term fiscal-reform challenges on their own.
不管伯南克和其他人多么不愿正视现实——也不管吵吵嚷嚷的政治家多想推卸政治责任——央行并不掌握有效工具，来解决因教育培训及实物资本投资不足而造成的失业危机。同样，央行也无法凭借一己之力应对债务威胁、修复破碎的家庭融资或解决中期财政改革的难题。
