How is marriage viewed as a social institution in The Importance of Being Earnest?i want to know all details about my question

Marriage is viewed as a social institution because that is
precisely what it was in the 19th century. In those days women would enter marriage by
offering a dowry in the form of money or properties to a potential husband. Often
families did this with other families who had lots of money. If you didn't have it, your
chances of obtaining any benefits from marrying money and property became lower and
lower. This also meant that your social standing will come tumbling down: You would not
be admitted in other homes as a visitor, people will talk about you, and you may end up
joining a nunnery or as a spinster, which was worst than being a prostitute
even.

In the case of Ernest when Lady Bracknell sat down to
ask him all sorts of questions about his finances, upbringing, etc, he mentioned the
fact that, although he had lots of money, he was orphaned and abandoned in a handbag.
This was problematic because, like Lady Bracknell said, her daughter cannot be married
off to a "parcel" and that Ernest needed to produce a father or a  mother quickly to be
able to consider his engagement. This was the way marriage was done: With names, last
names, amounts, and business transactions that will ensure that the family name and
money will continue to be long lasting.
