Scipio - knock me out, please do. I daresay you're right, one of those lovely homophone coincidences JA would have loved and not used.
Yes, the bigger the dowry, the bigger the income for the married couple - land and cash produce income. Dowries were supposed to be kept separate from DH's money, but abuses were rife, especially in the latter centuries when things got worse (sorry to be so vague) and men could get away with it more.
The Woman in White, recently on telly, is about this - wicked Lord Skint marries rich WiW then steals her dowry and locks her in a bin on her own money. Wilkie Collins wrote it as a battlecry against Married Woman's Property restrictions. He lived in a menage a trois and thought himself a feminist, tho I daresay his GFs disagreed.
By the early 19th cent women's rights over their own property, bodies and children had been pretty battered - successively eroded by law over centuries.
Reversal, as far as I know, which is not much, began in the 1850s. Slowly. It was still not great by the 20th cent - TS Eliot, incidentally, locked his wife in an asylum on her own money. In the 70s a man had to sign your mortgage application even though you paid every instalment yourself. Shows you how bad things had got. Goes without saying that women are still paid a third less for the same job and don't inherit anything like the sums men do. Basically, society doesn't give women much money. Most of the money in the world is taken and kept by men for themselves.
