To give a concrete example, it is compulsory for school-children in Wales to learn the Welsh language, even if they are not ethnically Welsh, and even though most people in Wales do not speak Welsh. This public policy choice is justified on the grounds of preserving Welsh culture. Whether or not you approve of this decision, it's clearly an allocation of limited time and money which could be put to other uses.
