See, to me, that is a dangerously malleable definition. "and make the most of their lives," can be slowly expanded to include complete and comprehensive, health care, college education (never mind the fact that everyone having a college education is extremely wasteful,) perhaps next will be roomy housing and cosmetic surgery (I doubt that last one, but your definition could encompass it.)

It also completely ignores the concept of limited resources. This is reflected in the sometimes encountered naive view that we could, theoretically, give anyone whatever surgery they needed. Those countries that have governmental health care have limits on what ages can get what treatments precisely because this isn't possible.
