Its depressing to make comparisons, but 99.9% of developers will never make half of what a specialized MD or successful lawyer or someone in finance might make.
What percentage of people with law or finance degrees to you think actually make what you seem to think people with law or finance degrees make?
Not to mention that by being a developer, I started earning money in my early 20's, without hefty university debt. Less risk (plenty people study for the bar and fail) and upfront costs.
There's also less chance of getting a casual 9-5 environment in finance.
