No, it is society and family that teaches perseverance. Or not, in the case of modern America. Teaching math has nothing to do with it.
I took calculus in high school. Since I graduated 40 years ago, I have never needed any concept beyond algebra and trig. I realize some fields would require it, but statistics would have been more useful to me than calculus.
That was my experience, as well. And, I only really needed trigonometry when I was developing an Excel worksheet to do aircraft navigation calculations.
Statistics became much more relevant to me later in my career, which required a lot of data analysis. I dusted off my college statistics book at first, and then set it aside as the 'Net became a more useful resource.
At Michigan State I was required to take, and pass, a statistics class that was aimed at broadcast majors (my major); I used it just enough in the following years to more than justify the time and modest cost. Even used it as a Navy public relations officer.
I think basic statistics is very useful, even if it only helps you understand that the lottery is not a valid retirement plan. :-)
