He did say he worked a lot to earn money when he was younger but he couldn't have earned that much
I'm curious about why suomi said he wouldn't have to study or work again.
He doesn't have to work, because he himself claimed that he has worked a lot when he was young/before he started HC'ing the shit out of RS. There is also a myth going around, which says that Suomi got a shitload of cash from heritage. I don't know if the latter is right, maybe Suomi will confirm this.
About the studying part, I know some facts about his study-life, I've heard this from a person who has met Suomi IRL, but because I respect other people's privacy, I'm not going to reveal anything about that. Unless Suomi allows it, or he himself says something about that.
I remember in lemar's troll video of "suomi live commentary" he said suomi's parents won the lottery but that was just a troll
