With that said, I'm not exactly sure what type of career path somebody studying, say, political science could embark on -- it seems to me that there's a lot more demand for accreditation in certain fields than there is demand for actual practitioners.
Computers are getting better at sales. Amazon doesn't have salespeople. Retailers barely have salespeople any more. Outside of real estate, cars, and financial products, what B2C companies do?
AWS sure as hell does
Selling to businesses, for example, pretty much requires salespeople. For example, I know someone in corporate real estate, and you wouldn't believe the type of shit the salespeople get away with there or how ridiculous their compensation is (especially compared to her, who does just as much work trying to win business when putting together the proposals those salespeople present).
Declining for sure, but high ticket B2C still has salespeople.
Home improvement, cosmetic surgery, cosmetic dentistry, vocational education, timeshares, boats, recreational vehicles, insurance, furniture, solar energy, hot tubs, pool tables, pianos, etc.
And a lot of stuff at the low end, home based seller angle...beauty, vacuum cleaners, organic, supplements , diets, and so forth.
I'm not so sure it matters. Even in engineering, college courses alone won't provide you with a worthwhile resume. In college, you have plenty of chances to build a CV worth hiring. You can do research, work on meaningful projects outside of class, get internships, etc. no matter what you want to study. All the people I knew who got jobs out of undergrad did some combination of the above regardless of their major. The important part was that they could point to concrete things that demonstrated their skills.
