KOLOS: You didn't believe all Klingons were soldiers?

ARCHER: I guess I did.

KOLOS: My father was a teacher. My mother, a biologist at the university. They encouraged me to take up the law. Now, all young people want to do is to take up weapons as soon as they can hold them. They're told there is honor in victory – any victory. What honor is there in a victory over a weaker opponent? Had Duras destroyed that ship, he would have been lauded as a hero of the Empire for murdering helpless refugees. We were a great society, not so long ago. When honor was earned through integrity and acts of true courage, not senseless bloodshed.

From ENT: Judgement

Worf talks about this in TNG as well. Being a Klingon isn't just about violence. Anything can be a battle if you view it as an internal struggle. Worf described to some other Klingons how he viewed just being the only Klingon in Starfleet as an inherent struggle, and that by being a good representative of the Klingon people in his role, he was being honourable.

Fighting the very laws of reality sounds way more challenging than fighting that dude over there.

But what about boring jobs. Are there Klingon janitors? Klingon repairmen? Klingon construction workers?

There have to be Klingon chefs, right? Isn't replicated gagh inferior? Is blood wine just blood or are there Klingon vinyards?

They didn't always have replicators so there must have been Klingon factory workers

It's the episode where Worf blows up that civilian ship on accident. I think it's Rules of Engagement.

I am thinking of the DS9 ep where Quark gets into Klingon financial shenanigans.

And I believe it's just the overcoming the challenge of building a house, declaring a "war on drugs" and actually winning it, discovering how to make an electromagnet as a way of conquering physics, getting into a fight over haggling on selling that rare Charizard card.

So same progress as Earth, just a different way of thinking? Probably totally inaccurate, but maybe a hint of Japanese culture?

Wait, does that mean they indirectly got it from the Dominion?

This might be a history misconception I'm spreading, but what if it is like Sparta, where there was a huge slave population upholding that martial society?

They have all those things, but they do not discuss it with outsiders.

I miss whomp

That's spectacular!

I figured they were more diverse before they started conquering other species. Military service seems to be pretty strongly associated with the nobility. My guess is that when they got some other worlds and species under their control Klingons as a whole became quasi-nobility and other species started filling menial jobs. This probably came to a head around the time of ENT. Some jobs, like lawyers and scientists, are probably restricted to Klingons for security reasons, but not as well respected since they're not traditional professions for nobles.

Which is why in Klingon Mythology the Klingons sleep their gods as they were more trouble than what they were worth.
