When my fiance and I moved in together we set up a joint bank account. All of our money goes to the joint and we give ourselves an "allowance" each month. We get the same allowance, which is plenty, and discuss large purchases from the shared pool. The main reason for the allowance is because we budget the pooled money weekly meaning that purchases aren't private. We don't need to be entirely in each others business so the allowance lets us make purchases without informing the other.

The way we think about this is that _any_ increase in either of our paychecks is a benefit for both of us. I'd love if my fiance made 10x what I did because that all comes back to benefit me too. I'm pretty easy to please though. My fiance is really into some expensive beauty products for example and we buy those out of the shared pool but I don't really care for much except having a good PC. Even if I suddenly got serious $$$ I think I'd pretty much continue doing the same stuff. I wouldn't even buy a new car.
