If your earning the big bucks but got no savings, your only got you're self to blame. Plenty of other ground staff not sitting on a million dollar payout already struggling before covid hit.
It all depends on where you live. Quite easy to be earning the big bucks in Sydney, live in a location that is say a 45 minute commute and have an average house and a massive mortgage. That's just the way it is. Not everyone wants to/can drive 2-3 hours to work to lower their cost of living.
As for the ground staff well they can go and find a better paying job if they don't like the one they have. Kinda stupid winging about a job which has no qualifications required and all you need is a bit of customer service experience at McDonalds or Coles etc and off you go compared to an airline pilot. It's almost a comical comparison really.......
