Some of us do invent. 8 patents and counting.
Vast majority don't.
Perhaps I can explain it this way, about 20% of people have careers. 80% of people have jobs.
They might even be important jobs. Certainly the guy who makes sure the gas main is properly sealed has an important job. But it is still just a job.
He is not creating anything new. Just making sure the old stuff does not vanish in a cloud of smoke.
Good thing he does not want to just work from home.
Or we would be seeing a lot more smoke and a lot less gas.
