I share the concern voiced by several sources in that article that using performance in AlgII as a predictor for success misses the correlation/causation distinction. Engineering, science, math, and medicine all require AlgII, and even a substantial portion of lawyers come from science rather than liberal arts backgrounds. So AlgII is a prerequisite for most high-paying jobs, and is thus a good predictor for success by correlation rather than causation.
