Unhappy with his post and superiors there, Leopold strove at all times when on tour to gain a better circumstance for his family. The family made quite a bit of money on that tour. Well, Mozart and Shakespeare didn't need any of these new-fangled copyright laws. If you were a contemporary of theirs and you attempted to perform one of Mozart's operas or Shakespeare's plays without permission or authorization, you would have heard from the authorities right quick. It's also interesting to note that in their time, laws governing the production and storage of raw meat were nothing like they are now, either.
More laws are often a good thing.
You've contradicted yourself on the above. I don't think I could make stuff up like this. Mozart didn't need a recording contract, of course, because there was no such thing as audio recording. The technology wasn't available to him, and it wasn't available to anybody. He also didn't need a car, an electric toothbrush, nylon, penicillin, or two-ply toilet paper.
