Are floor traders junkies?

I could be wrong but they seem like junkies to me all chasing a high they got from beating out the other guys. In some ways it's sad that the days of floor trading is over, but what value were they really providing to society? Their answer is "liquidity" but if that's true then they should embrace electronic trading. I suspect they are just sad because their drug supply disappeared. I think it's better this way because otherwise these people spend their lives producing nothing, and it is better that they are forced to find ways to put their talents into some real service.
