My career has looked like tech startup (fullstack programming) -> finance sales -> B2B tech sales -> unskilled labor -> skilled labor (HVAC/Electrician/Plumbing, etc. for OPSEC reasons, won't specify)
Skilled physical labor is where its at.
Unskilled labor is basically a few steps removed from being a slave. 10 hour days (many times 11-12) at bottom-barrel wages, working as fast as you can (because corporate tracks efficiency. Yes, it's actually quantified! HAHA), and getting injured no matter what. It's mind-numbing. I hated it.
Now I've been doing a skilled trade, and I feel rejuvenated from being burnt out of white collar/office shit. Get to work around 6-7am, leave around 2-6pm (depending on workload. Usually it's around 3. However, this is with paid overtime. Once you start making the big bucks, your overtime becomes obscene). If you work for a small shop/family-like environment it's very laid back. You develop the stamina needed in about 6-8 weeks, and after that you get very fast at everything physical you do.
There's a lot of learning involved (especially keeping up with your state's local building code), but once you know the code and how to use the tools, you basically don't need to relearn the latest way to build something, or spend weeks trying to wrap your head around a tool, or hours late at night wracking your brain trying to decipher shitty mandocs and undocumented APIs, or troubleshooting/debugging while simultaneously wanting to blow your brains out.
Everything is simple to learn, troubleshoot, and wrap your head around; it's all in the physical world.
Fuck office jobs. Fuck unskilled labor work. Being a farmer is almost like being a glorified landscaper.
Nonetheless, I don't see myself doing this forever, so I'm working on a side business so I can break out of the labor class, and join my fellow capital-owning brothers.
Also what you said applies to any office job and not just programming.
Physical labor maybe something that we enjoy but say running a farm requires insane amounts of it day in day out.
