If you get to see some of the details, defense (US) is expensive but there is very little profit compared to other industry. There is epic amount of inefficiencies which is where all that cost is eaten.

Or anything in manufacturing or food/beverage (see Nestle and water rights) production. I think most of tech has it pretty good. Tech has the potential for incredible amounts of bad, but this is limited to the handful that dominate social media (see Facebook and the civil war in Ethiopia) or, I don't know, the ones selling surveillance software to governments and law enforcement.

I thought ICT was terrible, so I decided I'd try the industrial side of things.

Ok, on the one hand, getting to play with cool robots, and eg using an actual forklift for debugging? Absolutely priceless, wouldn't trade it for the world.

But the ethical side of things? There's definitely ethics, don't get me wrong. Especially on the hardware side - necessary for safety after all. But the way software is sold and treated is ... different.
