When we talk about humans, in general, the outcomes are usually a little on the negative side. After all, we are Deuterostomes, those beings that start by being an asshole before anything else. And throughout the development of civilisations, being assholes have been a big trouble for us.
As we progressed this nature of people created a lot of jobs for many, there is always a silver lining to every dark cloud, like I always say.
On the epitome of being atrocious, we have created a job which should have never existed at all. Even the animal instincts define us as such that we would have never needed it, but then anything is possible. Others in the category include, pet rescue, rape/harassment counselling, etc.
Although the work spectrum of police is very wide, but the basic concept came out of our bad. The inception of law enforcement, like it says in the name, was to enforce laws, and laws were made to control our unacceptable behaviour, though not always. But in those other cases, the law-makers were the bad and thus such laws needed enforcement. Either way it's cause of us.
Yeah guys, these jobs are created because we ourselves are incapable of cleaning our own mess. Everywhere we go, we leave a trail of garbage and mostly don't even care to just dump in the waste basket, leave alone making sure the cleanliness of toilets when we leave after using them.
Need not justify anything at all about it. Only that it is yet another job created by the top level horrendous-ness.
Taking the behavior back a little where we are just assholes, Bouncers seems to be one interesting profession where they are paid to be assholes in return and neutralise the gesture. And for a fact, these guys are mostly pretty good and more strong mentally than physically, only they are required to be otherwise.
Blaming the inventor of elevators is the worst argument, they made it to make things easy for us but instead. Let's see what we did to make it happen, we pressed all the buttons after getting off, some of us played with emergency stuff, vandalized them too and finally used them as private space to make out and for quickies.
Unlike any other, this particular job is of unknown origin and gets tougher day by day. No more words are there to describe the horrors of doing it and being on the other side too.
