That is a common trend in all kinds of enforcement jobs. As the number of rule breakers gets lower, the rules get tougher to compensate. For police officers, security guards and bouncers it means that they will intervene in less and less serious offences. But it appears it works the same in other kinds of professions too. For example, dental health is improving around the world so dentists are spending more of their time with cosmetic issues because fewer patients have holes in their teeth. It's even the same in software development. What do you do when there are no major bugs to fix? You spend your time fixing all the minor irrelevant issues!
I think the empirical evidence is soundly against the idea of people being lazy. People will always find stuff to do because almost no one likes rolling their thumbs all day.
