I wondered the same thing. I'm no attorney either, 2 semesters of business law tells me athat a contract can't be slanted in favor of 1 party or it could be invalid / unenforcable / voidable.
Not necessarily. Bad contracts are negotiated everyday. (no better example than what we're talking about here). If the terms are within the law, both parties not coerced or misled and some form of consideration for each... it's fair game. Consider the oft-used token "1 dollar purchase" to achieve a legal sale and transfer of ownership. Doesn't get much more one-sided than that. But it's quite common.
As with many things, it's caveat emptor. We can all come up with examples of "bad deals" we've experienced, that doesn't make them invalid contracts. (there are of course exceptions, as is usually the case)
I'm not an attorney either... just speaking from my own business and personal experience.
