<p>Actually I mean sales trader simply wouldn't have such a large networth. Sales traders work on commissions/spreads and is more involved in providing liquidity for client orders rather than actually placing bets for the book (which is called prop trading). They are not fully flow traders either because they also directly interact with clients and try to make them to place bets (and thus generate commissions). Big money in banks nowadays is made by prop traders (although in some areas the lines between prop and flow are blurred). You may want to check out <a href="http://www.ibtalk.com%5B/url%5D">www.ibtalk.com</a> which has some good info on the work done by various departments in a bank. </p>
<p>Also venture capital is more comparable to banking than to trading. Trading is very narrowly focused.</p>
