If you work to develop something that makes Amazon better, first of all that's Amazon's property, didn't you read your employer's agreement?

Anyway, yeah you do it to get promoted in the company and a higher paying job. You do it to reduce your workload. My first job I got out of university I automated everything I could and ended up turning a 10 hour job into a 2 hour job then I played video games and watched football at work for the remainder of the 10 hour shift.

I'm not a commie but I'm against profit being the driving force of a society. Morality and striving toward being moral should be the main goal. People should want to invent because that's a reflection of their good character. Lazy dumb slobs with poor moral values should just get shit jobs anyway. They aren't going to invent anything anyway.
