It’s manifestly obvious that there is some fungability between jobs and enjoyable movies as far as net impact on the world. Trading 1 job for a movie that billions enjoy is an absolutely spectacular deal for instance, obviously worth it overall. Trading millions of jobs for a movie that millions enjoy is obviously a bad deal, since jobs are indeed much more valuable than watching a fun movie on a 1:1 basis. How does 5,000 jobs:5,000,000,000 movie enjoyment experiences measure up? Well, I don’t know for sure, but it’s certainly not as obvious as you two seem to be making it out.
What is clear is that a merger which loses X jobs and gives a bunch more characters to the MCU>>>>> a merger that loses about as many jobs without that benefit. Now maybe you’d rather live in a utopia where nobody ever lost jobs to mergers, but that isn’t really on the table.
