A question: maybe I misunderstood it in the essay! So you both pay your salary into one joint account and then each of you gets x% transfered to their own personal account? Doesnt Person A, that earns more think its unfair that Person B gets the same amount for their own personal leisure usage? How is it different from Person A paying for most things like in your example with your previous relationships, to the solution you suggest, since i suppose Person A ends up paying for more joint expenses and gets out as much into their leisure account as Person B? I hope you understand my questions :) Thanks again.
