To be sure, if tax rates were decreased permanently this year, there would initially be a strongly positive effect on labor supplied. But there would also be a positive effect on saving and thus on wealth next year and beyond.
固然，若今年税率持续下降的话，那么一开始它将会对可供劳动力产生尤为积极的影响。但是那也会对储蓄产生积极作用，到明年乃至今后，这种作用就会影响到财富积累。从长期来看，财富与税后工资有以相同比例增长的趋势，其对工作的影响将消失。
