Is economics a useless degreeWatch
Will it help you not having to hire people? Probably not. But it depends on the type of business lol.
Learning economics is not useless. You learn things that may seem useless but it gives you a greater understanding of the subject. Whereas if you just self teach everything, you tend to only learn what you feel need to know. You dont get that wider knowledge.
Also you dont get the connections either.
I want to start my business one day and I need to know as much as I can do that I don’t have to pay as many people when I am starting off. Will economics help with that?
Personally I'd recommend studying for an economics or business degree and working somewhere for at least the first five years of your career (depending on what you intend on doing). Running your own company from day one is risky. It could easily go bust, bankrupt you and cause you a world of problems if you're inexperienced. Having that degree opens your options to work elsewhere if worst case scenario does happen.
Where economics is useful as a degree, besides the usual "transferable" skills a degree offers, is in the numerical skillset, as well as the commercial acumen, it confers. It's a very logic-heavy discipline. You'll get out of it what you put into it, but IMO it's one of the least "useless" degrees out there and the skills it develops are in high demand by employers.
