The second idea is fiscal realism. Budgetary prudence is both desirable (unsustainable deficits owe their name to the fact that they cannot be sustained) and progressive (when things blow up, it is the poor and the vulnerable who suffer the most).
第二个思想是财政现实主义。预算审慎值得追求（不可持续的赤字顾名思义是无法持续下去的），也具有进步性（当情况转坏时，穷人和脆弱群体受创最重）。
