Personally I feel that the "rest of society" is getting way too little money vs. us getting way too much (opinion based on the fact that profits/productivity have outgrown salaries for too long).
When I was working at a non-FAANG for normal pay, I was basically living the exact same lifestyle as my dockworker grandfather. I could afford a house and car, wife didn't have to work, one vacation per year, moderate savings.
There is another name for it - getting shafted
A good engineer can make a great deal of money for the company, far more than a plumber ever could.
I.e. an engineer has leverage.
Installing a toilet is more like wroting a bash/shell script that is 99% googleable - most people can figure it out in a weekend
Writing a whole applocation is more like doing plumbing for an industrial installation. that handles hangerous chemicals
It works like this. If I could hire bob for $10, but he produces $100 worth of value, hell yes I'm going to hire Bob. But Evil Corp sees that and thinks "damn, I want Bob to contribute $100 to my bottom line, so I'll hire him away from Bright Corp by enticing him with $20 pay.
Then, BadAss Corp thinks the same thing, and hires Bob away for $30. This process repeats until Bob's pay + opportunity cost == $100.
However, there is a point of diminishing value being added. If lots of Bobs are available, the incremental value (leverage) each one adds becomes less. There are only so many redesigns of one's database that improve productivity much.
As you can see, the more Bobs, the less they'll get paid. Until Frank comes along with a new idea for adding value, and starts the process over again.
I.e. an engineer who has a track record of delivering value can command a much higher salary. I know one who got a million dollar salary.
This is also why CEOs get paid so much. Leverage. Nadella is a prime example. As an MSFT shareholder, I'd say he was darn well worth it.
I usually find that this typically stops at something like $10 for most people. Despite people being “valuable for millions” offers for that much don’t magically seem to spring up. The people I know making a million a year typically make the company tens of millions…
