I agree.
I am continually confused about where Miranda's money went. Given that she made partner early in the SATC series (series 2 I think), she'd have been a fairly senior equity partner by the start of the movies and easily on 7 figures by the time she left her first firm in Movie 2. Granted she moved to another firm that was a bit more friendly at the end of the second movie, but I doubt she took too much of a salary hit.
Miranda had a lovely Manhattan apartment for years and probably made a lot of money on the sale, even if she had a mortgage, They bought the house in Brooklyn quite a few years before the area really took off and house prices soared. Never sold it/upgraded, Steve did all the work on it - as he yelled at her in the last series! Had the house for at least 17 years. I would be amazed if it had a mortgage or anything other than a very small mortgage when they sold it. I would have hoped she'd have put in place all the necessary legal measures to protect her equity on divorce, since Steve appears to have paid in zero (name not on the mortgage), as well as having a decent pre-nup in place.
Steve's bar was financed by Aiden, and there's no suggestion Miranda sank any money into it. For that matter, where did all Steve's money go?18-20 years of running a successful Manhattan bar - he must have made something.
One child. presumably privately educated. Not at college, so no funds spent there. Granted they had to pay for Magda's salary for years and Mary's care fees at the end. But still, that's not going to burn through a top lawyer's equity share to the extent that they are struggling for money. I don't understand how they ended up in a position where Miranda was having to sofa surf post Che, and is now living in a Airbnb and not buying a place of her own.
