I guess it can only be decided on an individual basis after all.
I think there was a similar discussion here recently, about somebody breaking lose all hell because a company screwed him over 20$. On the one hand it didn't make sense, on the other hand society needs somebody to step up and make a stink, otherwise companies that rip us off small amounts of money would proliferate.
I am not experienced with lawyers. It would be nice if it would be possible to just delegate this nasty stuff to somebody and forget about it (for a fixed fee?). I suppose rich people would just tell their secretaries to deal with it... Maybe some Indian company could step up and provide that service for cheap? Or would it work like that if you already had an established relationship with a lawyer you trust? First negotiations with lawyers seem painful.
