they're louder.

It might just be me, but I've always wondered why flight attendants come across so loudly and clearly over the airplane's sound system and the pilots don't. 

Is that intentional? 
Does it speak to who is more important or vital? 

But, it does speak to a bigger issue. Why do we often hand the microphone to someone other than the one actually taking us where we want to go? 

There are some decent reasons, I suppose, but I'm more eager to hear from the woman flying the plane, than the man telling me how to buckle my seatbelt.
