The makers didn't ignore anyone's request!!
I have read through nearly every single one of the suggestion posts for VV (with God and LDW as my witness), and you would not believe how much Arthur has worked to meet the many requests that were made. And every single thing you ask for takes a lot of coding. Some things are harder to implement than others.

Money and careers do not make a family. A family is made when people care about each other. In fact, in most of real life, money and careers can cause conflict between people.

As for the woman's ability to advance a mother's career, there are options. As it was even said here, you can buy the magazine for her career. She can help the family gain money by gathering the collectibles. You can have dad stop working during that time and help around the house, so that both can work on advancing their careers at the same time. There are plenty of options.
