Of course a guests safety is a concern, wouldn't that be the essence of guiding, if it was safe why would you need a guide? To hire a guide is to admit that you are undertaking something above your own abilities and of course you rely on your guide to get you safely through.
To question these outfitters on their morals, risking lives for money, is just wrong. Outfitters that run this stuff know that any death is not worth the money and do all they can make sure that people don't get in over their head. As to guides showing off their ability that's not what it's about, and if that's why your in this business I hope you get out before you hurt someone, it's about being confident and knowing you can do whatever it takes to get these people through, unfortunately sometimes the river has other ideas and it always wins.
The two incidents you have been speaking of don't even come close to showing that class V guides and outfitters are in it for the money or bravado. In Pine Creek the fatality was a family member of the safety kayaker, who would have nothing to gain by his fathers participation in the trip, in fact if the guide sucked he'd probably tell his dad not to go. As for the Animas I've got to imagine that Darrell would be fine if he didn't care about his crew. If the compay's owner was in it for the money he wouldn't bother with the Upper, he'd crank 'em out on the Lower or maybe somwhere else, like Brown's Canyon.
Just wanted to mention that I don't know any of those involved in the above incidents and am speaking from my own river experiences. I don't even guide anymore or even care for comercial rafting much but to question the integrity of the people guiding/selling this stuff you are wrong.
