The thing that's interesting though, is on the consulting side, as my rates and overall project cost have increased, the time investment to close a sale has also gone up. Meanwhile, if you go for a more expensive & specialized skillset, there's also a time investment on the marketing & outreach front.
Basically, in my experience, there's a small handful of people who've managed to carve out a niche where they can work low hours and make a high hourly rate, but they're few and far between, and investing in passive income streams is really the way to go.
That said, I _really hate_ managing rental properties instead of slinging code, but in terms of dollar per hour there's no comparison.
They seem to be the loud minority on here though. I guess if you get a sweet gig like that, you will find lots of time to post on HN. I know I'd brag about it too if I was in that situation.
