A colleague of mine has lived in the USA for years. When visiting the local office here he commented, paraphrased "the craziest thing there is that at any given time you can make a tiny mistake, and the rest of your life is messed up completely". I think ruining random individuals' lives is not a sign of a good legal system. There are some other systems that try to avoid that more, though of course that still happens, and there are some things to be discussed on what kind of contracts are legal etc. There are of course different legal traditions in the world and so on too, in the bigger picture, but still, it seems so disastrous to the individual looking from outside.
