Inevitably scarce resources are better invested in deciding which [patent] applications are worth filing and seeking the broadest defensible claims for those that are chosen. Whether a patent can be obtained for less than, say, $10,000 is the wrong question. Whether a patent is worth having is the better question—particularly from the standpoint of prospective licensees.
