Jesus was not a prophet. That would be like the bosses son working as a janitor.
John the Baptist was a prophet Jesus said so.
In the realm of humans, many a wise boss does indeed give his son experience being a janitor. It helps the son understand the importance of each job in the business, even the lowliest.
In the spiritual realm, the janitor analogy also works because Jesus became a lowly man, born in a stable, buried in a borrowed tomb.
