"At some point the jobs no longer make sense."

Blockbuster disappeared because the technology it was built upon became obsolete. It also didn't require specialized labour skills - the employees just took their retail experience across the street.

edit: I'm reading some other comments about drive trains and EVs & reduced manufacturing requirements due to it. That's interesting. Maybe I should read about this more
