Yup - bottom rung employees in any industry end up working hard. Analysts are pretty low down the food chain.
But traders - depends what you mean by that? People that work positions for other firms or those on prop desks? Those that are employed to fill positions are really doing grunt work. Traders on prop desks somewhat different, they do more coke and probably aren't hungry.

Managing director of any hedge fund (I can give you a list of 2 that I worked for and their MD's either quit or practically jumped out of a window)
That's a short list of wall street workers that barely eat.

A friend brother runs a hedge fund in NY and has a very steady family oriented life. "Hedge fund" is a pretty wide net - it's effectively a classification of funds that are less regulated than mutual funds. There is no reason to think that any particular hedge fund would even be trading on a daily basis.
I know of a boutique fund that does nothing more than act as a big prop - loaning out money to traders for a share of the return. One chap that I bump into socially on occasion (but nothing like a friend) trades $30M of their money. They effectively take risk and whine when he's on a less than stellar run. On a daily basis, they don't do an awful lot.
I personally trade Eurex (EuroStoxx and Bund) and the CME (spoos) and the activity INVARIABLY dies at lunchtime - although it's just been dead all day today. So 12pm-2pm there's very little activity. Cause so many traders are at lunch.
In fact, I really wish they wouldn't take lunches and the market would zip about all day.
