The money issues in this show doesn't make any sense, do you agree ?

I just did a rewatch of the show and got so confused :

Grace and Frankie struggle to get a $75K loan, yet they live in a multi-million-dollar beach house with probably high maintenance costs.

Robert donates $20K and then has to become an Uber driver because it put him and Sol in financial trouble—even though they were successful lawyers with a multi-million-dollar home. That’s a lot for most people, but not for them; they’re not middle class.

Brianna sells her company for a hefty sum, yet the money seems to vanish, forcing her to turn to her high school nemesis for funding.

It just doesn’t add up. I get that the creators wanted to show them struggling for narrative purposes, but it wasn’t well executed—these moments were really confusing. Am I alone ?
