Software keeps working after the work is done. That’s the key differentiator, not the brain power. This leads to economies of scale on two fronts.

1) scale for the low end. As an engineer, I’ve made a game where I have customers worldwide that pay me something like 25 cents a week. A lawyer can’t really do work that scales out at the low end like that. It’s not a brain power thing, it’s just the nature of the work product.

2) at the high end, a big company like Google or a financial institution can keep hiring programmers at say $100k, and have them produce tiny detailed enhancements that produce say 150k or or more of revenue per year over a multi year period. Most large systems can always sustain a little more enhancement that will produce an optimization of revenue.

I think this is the key difference between programming and other kinds of work. Programming is scalable at both the low end (distributable to very cheap consumers) and the high end (can always get more revenue through optimization). And at both ends of this spectrum the machine keeps earning money even when the programmer is sleeping or working on a new project.

Software doesn't keep running indefinitely. It has a shelf life of a few decades at the most, and usually just a few years.

Programmers definitely have leverage due to scale, but lawyers also have a lot of leverage when dealing with cases that have large $$$ amounts tied to them. Traders obviously have leverage by using large quantities of capital in their trades.

A lawyer can make a small modification to a drug patent that helps a company earn for example $2B a year for 15 years rather than 12

A lawyer can make a change in a corporate structure to lower a company's tax rate indefinitely

From the perspective of lawyers adding value to the law firm, a good lawyer can do this with dozens or hundreds of clients a year, and increase the firms revenue by bringing in tons of new clients. Creative lawyers can also figure out a way to differentiate themselves in a particular sector, like tech startups, and one lawyer who becomes a leader in an area can add millions in rev to the firm a year, for many years, by bringing in new business

Some law firms also take equity, and good decisions about when to do this can bring in huge windfalls
