What are some undeniably GOOD things about the United States?

A "can-do" spirit (sometimes arrogantly so, however it is encouraged, not "put in it's place")

This is sometimes congruent with "the entrepreneurial spirit" in which, rather than waiting for a boss with a plan, one makes ones own plan and seeks to put it into action and find the funding for it.

There is a dark side to this same social trait, but in keeping with this thread, the positive side is a sense of personal ownership and self-investment in ones life activities.
