Why should I stay at University?

I'm currently in my second year of three studying accounting at university which I have an interest in and doing fairly well in my courses but I'm having trouble finding an incentive to finish my degree, I don't see what benefits a job that pays $60,000 a year would have over one that pays $20,000 at an entry-level position doing basic work. I don't live a luxurious lifestyle, my biggest expense would probably be my gym membership which is $500 a year. Would women prefer someone with a high paying salary?
