Economic policy must strike a balance between ideals and needs. It includes decisions about government spending/taxation, about redistribution of income, and the supply of money. Economic policy is implemented/administered by the government (a course of action that is intended to influence/control the behavior of the economy). And it should seek a balance between ideals and needs of a society/a nation.
Ideals are values/principles that guide conduct.
Needs are goods/services that are required.
