Do we really need algebra 2 and calculus?

In #articles

From time to time I hear proposals to restructure math or science secondary education. Two examples are an article in slate about algebra 2 and a popular ted talk about calculus. In each case, the argument goes that statistics - and I would add probability - is far more useful to a larger fraction of students than, say, calculus or algebra 2. I think the argument has merit, although I think that algebra 2 is probably needed to do much of statistics and I should stress that those students going into the sciences or engineering really still need both calculus and statistics.

For an interesting discussion, see this Quora thread. None of the counter arguments are convinving to me but there is some nuance to the argument expressed that I feel is productive.
