How is Johnny able to make a living

Valley kids are pretty wealthy. He had about two dozen students at the height if his dojo and they likely paid very well.

He does not need to make a living he is getting paid to act in a Netflix series.

Stingray has money to burn. Who knows what kind of premium he was charged. He is obviously rich since he lives in an affluent area.

Hes, actually the real Johnny from the original movie, and has probably made money o ...

Oh wait.. I see what you mean.. Oo Hmmm, He's a pimp for sidekicks?

Ionno

Dont forget, in the first season his rich stepdad offered to write him a sizeable check which he turned down because he was an abusive dad. But Johnny ended up taking the money. Maybe he had some of that money left over, and he gets money from his students.

My sister went to a kickboxing class and it was expensive. So Johnny could make money charging students (and changing prices depending on the students income). You'll notice many martial arts studios sites want you to send them your contact info so they can discuss price personally with you. I searched several and no program prices were listed...which to me says its expensive.

I've wondered this since the end of S2 when Kreese kicked him out of Cobra Kai...even when he was trying to get a job at the beginning of S3, he explicitly said it was just to help pay for Miguel's surgery and not for himself.

I think we're just supposed to assume he has a lot of savings.

Largely a plot hole, but I am pretty sure at one point its mentioned there was multiple class groups, just we only got to see one of them, so if thats what happened its possible by the time johnny pays back his step dad he has loads of cash stashed away somewhere.

There is also the possibility danny paid his bills when the dojo's merged, not beyond the impossible given he had given him 2 cars and a free repair at that point.
