I think we've generally been pretty successful, overall as a Nation because virtually everyone involved in making it one had to be a tough son of a B word. Now that things have gotten comfortable, the same kinds of ethics and ideals, not to mention learning processes have been either watered down or removed entirely. Life isn't all about "being OK". Sometimes life truly sucks, things are unfair and often the bad guy wins. To avoid that, "we" used to try to change the conditions responsible. Now, someone somewhere generally makes excuses for them and the flow continues on. I have nothing against progress. At the same time, I don't think becoming a nation of flabby milquetoasts is progress. Unfortunately, a lot of the rest of the world is perfectly willing to do what it takes to win.
Freely accepting losing, or eliminating the possibility of it is not IMO helping anyone learn anything.
