I'm going to add more to this cause the idea of entry level jobs teaching skills you need to work at other jobs isn't sitting right with me.

As a rule, the only skill entry level jobs teach anymore that apply to future jobs is how to eat shit and keep going. Every single habit you would learn would need to be unlearned to be valuable in skilled labor. You need to be independent and able to think of novel solutions to provide value at higher skilled jobs. Entry level jobs will grind you up and fire you under some made up offense so you can't even get unemployment. You succeed by being as close to a robot as possible.
