It is part of being an adult, but many adults are deficient in adult-like things. And really, if nobody ever tells new adults stuff like this, how are they supposed to know?
The only real position I see here is something like arethuza discussed [0] where the employer reimburses the employee for legal fees related to reviewing and negotiating the contract. Though questions of "when does this apply" are still unsolved.
Better education would be another good step. WTF Are Contracts 101 should be a required course at every high school, along with WTF Are Credit Cards, WTF is Voting, and How TF Do Taxes Work.
