I'm not sure you what you mean. If you're working somewhere like Netflix I'm assuming the median employee is quite good, so "scaling down" your output to match that doesn't really make sense to me.
These employees are optimizing for free time, not salary. As someone who thinks big tech pays ridiculously more than is necessary for a comfortable lifestyle, if I could work 1 day a week for 1/5 the pay I would (I understand why working so little would likely not make sense, I am just fantasizing).
10x more productive is probably a poor way to phrase what I really mean. 10x more impactful probably captures what I mean better.
I used to work full time (50 hour week including commute) for a company with a really high-performing software culture full time, and quit to do my own thing just before COVID.
I now work about 20 hours a week and pull in a slightly higher wage compared to before. Better yet, any productivity improvements go directly to the bottom line, so I experience more wage growth in a month now than I did in a year back in industry.
