I think you maybe missing the point Metro man is trying to make. It is hard and very expensive to become an airline pilot. $100 000 would be about the minimum training required to sit in the right hand seat with the minimum hours, even in a regional.
To replace a flight attendant with some one off the street takes about 6 weeks with line training (ish). To replace a First officer with a person off the street would take approximately 1 year just for the licence before the 2-3Months of endorsement and line training. To replace a Captain with someone off the street would take….minimum 3 years just to obtain the licence, most likely 5 for the minimum standard. I’m not sure how long it takes to learn how to pack bags in the back, when I did it they just assumed I knew what I was doing
