I've watched my share of videos from pilots explaining how accidents occur and what I have learned is that air traffic was always meant to have backups and redundancies. When there is an accident, it is often many different systems all failing. Unfortunately, the understaffing is a very large hole in the safety netting, allowing even minor oversights to turn into fatalities.
Unfortunately, the public will often look to the last person in the chain expecting the answers to how it all went wrong even when the issue stems from staffing cuts and budget cuts. And the last person in the chain will often be left with guilt and pain thinking they could have done something different when it was all just a matter of time
