Earlier quoted context omitted.
My impression is that traders mainly have a much easier time quantifying their value. When you can say "look, I literally made $10,000 today and $8,000 yesterday", it's easy to negotiate for a significant chunk of that in compensation. Your leaving would have a very direct effect on the bottom line. As a software developer, the value you provide is not quantifiable like that. Everyone works on the product, sure, but…
So it seems you are better off working in a profession with a very clear quantifiable performance metrics. Software development is not one of them unless you work for your own company. I am curious about making a list of professions that have quantifiable performance metrics. 1.Sales and Marketing 2.SEO 3.Bloggers 4 ..
Sales: the highest paid people at an enterprise software company, excluding people who joined really early and have stock grants to match, are the commissioned sales force. I met a gentleman who doesn't speak Japanese who nonetheless was I Can't Believe He's Not Tony Stark's #2 sales rep in Japan. Let me throw out a number for sales picked out of the ether: $50 million in a year. Let me throw out a second number, picked from the industry: 6% commission rate.
SEO: Most of the really good ones work for themselves rather than working at an agency or an in-house SEO team. I am friends with a couple of them. One once lamented his lack of programming skill, said that I was the most talented marketer among people with programming skill he knew, and made me this proposition: "You would be a very, very effective black hat. I'll stake you with a million. You pay me half of what you make." (I didn't take him up on it.)
Bloggers: The overwhelming majority make nothing. Then again, most are not running businesses. There are some businesses which have a blog as one portion of the business which are Quite Lucrative Indeed. One I'm aware of has revenue roughly equivalent to an enterprise software company with a few dozen employees. (Again, though, the blog is a small portion of that business, even though readers might not know that.)
