Although my profession may not be the oldest, it was already the brunt of jokes and bad-mouthing even in quite ancient times.  Here’s a passage I came across yesterday, which sounds so relevant still today:

We earned our pension rights – and was that enough? It wasn’t. Our claims are contested, we’re dragged into court, humiliated by smart-arse, beardless barristers who sweep us aside like fluff, like chaff. — Aristophanes, Acharnians (425 B.C.)

Sounds like an editorial in the New York Times!  Aristophanes’ anti-war theme, which is the main theme of many of his plays, also resounds in today’s world.
