The industry doesn't want to make software crack proof, they just want to make money. Typically, in the case of games, is is about "when", not "if", they know it will be cracked eventually, but they want to hold long enough to secure their launch sales, which is where they make most of the money. It is even common to remove DRM after a few months, because it is not worth it.

As for enterprise software, pros usually don't want the potential legal trouble associated with cracked software, and dongles are just about not making is easy to violate the licence by accident.
