The only problem with this example is not every software engineer has the ability to be an entrepreneur. Sure, they can create monumental value for their employers, but there are some people that just can't be founders or cofounders or anything more simply because of how they are. I know quite a few people like this. At the end of the day, it takes a variety of personality traits, skills, brains, and a slew of other things to create a well rounded individual who can maximize value. Outside of this, no matter how much value you're adding to your employer, how can you honestly say you're worth more.
