Point 1 makes sense, to the degree that it's true. Programmers are typically too far removed from actual transactions to get paid in the way that sales, bankers, real estate agents, etc. are paid. Thus, measuring what they're actually responsible for is difficult. To the extent it can be done at that level of abstraction, I'd argue that programmers are actually very over-represented in being paid based on hard outcomes. I haven't heard of any other profession with such a focus on equity grants.
