There should be certain base rights that are protected in any contract. For example, at one extreme, selling yourself into slavery shouldn’t be recognized by the courts.

Large organizations have more resources to screw over smaller organizations and individuals, so if we’re going to favor one, we should favor the smaller party.

I’m generally a fan of minimal government interference, but contracts are one area where people can easily get screwed over. I think governments absolutely have a place in arbitrating contract disputes, and part of that is deciding what is and isn’t a valid contract.

One thing that I think can help is requiring contracts to have a legally binding summary that is easily understandable by the average person. Anything that only exists in fine print would likely be unenforceable unless a reasonable person would expect it to be there. So for employment, the company would need to be upfront about their unionization policy, out it would likely be an unenforceable part of the contract. I don’t know the details of how that could work in practice, but the fact is that many people don’t understand what they’re agreeing to when they sign contracts.
