If your sitting on the beach watching the riptide take your kid and a lifeguard is going full speed to safe them, risking their own life, 300K wouldn't seem like a bit too much
If my kids had been caught in a rip tide, I would not be have been sitting on the beach watching - it is my job to protect them at the beach and I would have been in the rip. If a lifeguard were in there trying, he would not so much be risking his life as some heroic figure - he would be doing what he signed up, was trained and paid to do. No matter the amount of his salary.
