They are tracked but aren’t a “first class” statistic like GDP is as far as measuring the “health” of a nation is concerned.
Republicans in 2017 suddenly talked about how great stock returns / GDP / unemployment were doing when they spent 8 years saying they didn't reflect the true economy and the jobless rate was abominable. Now democrats are focusing on median income growth / GINI index / student loan default rates etc after saying everything was great for years. Statistics are just used as tools to accomplish policy goals and win arguments.
