> Those worries you mention exist on both worlds equally. What if my startup fails?

This cannot be serious. I've worked at startups, and the answer is: there are 50 other companies within 10 blocks who are falling over themselves to hire programmers, especially one with the gumption to try a startup. I've never heard of anyone who worked at a tech startup who then had trouble finding other employment after it failed.

If your biggest "worry" at work is that you might not become a millionaire and may have to fall back on a $150K/yr job, I really don't know how to respond, because that is nothing at all like the worries faced by people working in labor.

You're being pretty quick to judge here.

I've never worked on a startup and have no intention to do it. I live in a poor country where the average developer earns $8k/year and very few of us have any fallback. Mentioning startups was a way to relate to people here on HN.

If you don't focus on the specifics I bet you can come up with examples that relate to you and my argument still stands. Everyone has a different worry. Putting one's worries on a pedestal and discarding everyone else's as "not as bad" is pretty shallow to me.

Even when everything appears to be repetitive it is never repetitive. You should just try a work holiday visa on a country where you want to learn a language and work at a farm. It still won’t reflect all the stress that means just changing one provider, investing in new technology from all those companies that want to make profit on you for and never be sure on whether this year you are really not going to make it anymore, knowing you are already at the bottom of the chain (primary sector) and you start considering closing everything right before getting into bankruptcy. And your friends still believe you are ok because “you work in the nature” and if you are an owner you are very likely to get the whole year salary at once and they cannot understand why being cheap is just a way of survive.
