The increase could pay for more enforcement of the fees
I doubt very much if the government makes much from these fees. By the time you add the cost of developing regulations, collecting fees, inspection and enforcement etc.
But rules and regulations, processes and procedures are what has made us what we are today.
I personally am disgusted that people can walk on footpaths without any licensing whatsoever. Thousands of these unlicensed pedestrians get killed every year. Not to mention the billions spent maintaining footpaths throughout the country. Something should be done about it.
