I'm not really sure if you want advice or to vent. If you don't want job advice, please ignore the rest of my comment.
An option is looking at remote work that is technical, but not related to your degree/what you want to do. It won't be a fun experience but it helps pay bills.
Something like data entry or technical writing doesn't have much of a barrier to entry other than having a technical degree.
Another option is assembly/factory type work. This one is very location dependent, but there are stuff like PCB houses where if you know how to solder, you can probably find work. Or welding or something since you're a MechE. It isn't great pay, but it is usually more than retail.
Are these workers making weapons? The article says this factory is for Boeing's passenger jets.
