A few minutes after I said that and the person long gone; I got to thinking...
The person had told me about their work. I no longer recall what it was they do.
I made the comment, "Someone's got to do it."
The way it's worded, after I thought about it, makes a person feel less important, or makes their work seem less important. --- After all, someone has to do it.
All work (even the seeming less important) is important.
The difference between the cleaning crew and the president is that the cleaning crew is more important. If it were not for them, a president (corporation or government) would end up working in fully cluttered and dirty places, or spend most of their time cleaning up the place and far less time properly running their enterprise or government.
When we tend toward worshiping an employee of our (such as a president, legislator, or judge) they begin to act like gods and begin interfering in all aspect of our lives, rather than do the job for they were hired.
Many decades ago, in these united States of America, we began treating our politicians like royalty. Now, they treat us like their servants and subjects.
