Im a social sciences student (aka sociology) and it is most certainly not useless, its just that it doesnt have as many routes to follow, i myself want to graudate and get a PhD so i can be a political science professor, the wage is good and i love teaching and politics, but other than the academy route you dont have much else to do that i know of, you can either become a politician, writer or a political analyst, each of those requiring you to be a 1 in a 100.000 to "do well" (which by itself is a relative term, not to jordan peterson the text but what does one mean by doing well in life), but yeah, if we are talking about importance, without social science/political science/sociology we would not be able to understand society, the economy and how to do better as a civilization
