Doesn't matter if she's educated or not. Everything depends on personality and upbringing.
Some Sri Lankan women earn more than the husband but expect the husband to spend for everything. They wouldn't spend even a cent of their money on the family or common expenses (loans, bills, food, shopping etc.). Instead, they buy clothes, shoes and jewellery. As a result, the husband cannot develop himself or improve the family.
There are also women who don't earn much but voluntarily spend their money on the family. Rare in Sri Lanka but I know a few.
Some educated women have an ego and try to act superior to their husband. But there are also women whom, despite being highly educated, respect the husband and support the husband.
It all depends on the individual and not on the job or education.
Pro tip: Never tell your wife exactly how much you earn. Always keep a bank account your wife is not aware of. If you have investments such as properties, make sure there's at least one investment your wife doesn't know about.
