Sure, the job is simple enough not everyone can do it. If they could, they would. Stop selling yourself short. If anyone were able to do it, the problems you listed above wouldn't exist. In fact, the OP never would've started the topic.
I don't know why you're being so sensitive. You asked what planet I'm from and I informed you. Modern day FedEx not "back in my day" FedEx. If you're really that interested in showing everyone how it's done, you can always reapply. Then come back and tell me about dock culture and how much everyone appreciates your input.
This discussion has already been had here a million times. You're either doing the job currently assigned to you or you're not. I wasn't superman or anything, but maybe at least take pride in what you do and don't bail out with "well if he's not gonna do it then neither am I!" only to go on complaining about the poor quality of output.
If that sounds smug it's totally unintentional, but just kind of the way it is...at any job.
