Humor is difficult.
It’s tough when it’s actually a bad joke or they are telling it badly, but they find it funny.
If it’s a genuinely funny situation / retelling, both of you laughing about the same thing and also about how the person in question is struggling to breathe because they have to laugh so much, that’s funny.
But it really really really depends.
In a sense yes. Once a company has captured the entire (global) economy, including banking, it would control who to give credit to, who to employ, what to pay them, what their own products are priced.
They could at most reap as “profit” what they give out in credit and payment.
There may be sub-limits for capturing entire industries.
