i normally get bothered by gross off-topic posting but since this is actually important to your life i'll throw in my opinion.
i'm in a similar situation, graduating in may with a liberal arts degree. my first semester of school, i originally applied for and got accepted to business school (undergrad) for lack of having anything better in mind but was already skeptical about actually liking it. i took one course and decided it wasn't for me. i could have probably gotten into any undergrad college at my university (except specialized ones that would need a good portfolio). had been pressured for a long time to do engineering due to my really good history in maths and the many well paying jobs that are available to engineers. instead, i landed in liberal arts. i chose it because it had the subjects that interested me the most. i can honestly say that it was one of the best decisions of my life. i value everything i learned doing that much more than anything i would have found elsewhere (some more than others though). i have other friends that did engineering and hated it, fortunately dropping it before committing.
now that i'm going to be done soon, i'm not sure what i want for my career either. but, two things differ between us that i suggest you take into consideration: i'm not moving home - i'm moving to where i want to live, and i'm not taking a year off, i'm going to be done with school indefinitely. on the former point i gather you're moving in with your family to save money. i can understand that, but you should explore other options before committing to it. if you don't want to be there, you don't really have to be. on the latter point i still have lots of interest in going to graduate school, but i don't know what i would want to go for, and i'm not about to pay a lot of money for an education in something i don't like so i can end up working at a job i don't like. yeah, i probably will have some difficulty finding a decent job, and it will almost definitely pay less than had i majored in a subject known for its job prospects after graduation. but none of this bothers me that much. beyond offering us a certain degree of comfortability (and this doesn't require a ton of it), simply having more money doesn't really make us happy. many people put a much greater importance on it than they will admit (even to themselves). instead it plays/reinforces our association between consumption and satisfaction and that gives us the impression of happiness that they probably don't have. notice how people subscribe to this mindset never seem to have enough money even though sometimes they're ludicrously rich?
i don't have a problem with people going to engineering school, business school, med school, law school, etc. i have a problem when people do it for the wrong reasons (i.e. when they're not really interested in the subject). i'll just add that our choosing of careers like this isn't necessarily based solely on money/jobs. there's another aspect of prestige, (falsely) perceived lifestyle, and longheld aspirations that draw us to these things. if i recall correctly reedo and mikey, you've both had your post-grad plans in mind for a long time. unless i'm mistaken on that, you're not the same person you were when you originally were making those plans. you can't expect the freshman, sophomore, or high schooler to really know what he wants to do with his life. at least for me, the knowledge i gained as an undergrad has taught me a lot about myself in this sense.
admittedly, i was somewhat privileged in the costs of my college education. i know that for those taking out loans it can be difficult to specialize in something you know will lead to prolonged debt compared to other choices. i won't get into them all, but i have many more opinions about problems of higher education in the u.s.... for this one i'll only say that complete reform of the funding/financial/tuition matters at american universities seems like something that really needs to be more actively approached.
