True, in the US, as in most existing federal states, the federal budget redistributes income across regions, thus offsetting at least part of the interregional differences in income. But, while this has been repeatedly documented in many cases, the inference that redistribution is equivalent to a shock absorber is wrong.
的确，美国和大部分联邦国家一样，其联邦预算可以在各地区间再分配收入，从而抵消至少部分跨地区收入差异。但是，尽管这一点被一再提及，却没人注意到再分配等于冲击吸收器这一看法是错误的。
