Our mother's generation can share joys and sorrows, but we don't have the courage. We can only share weal and woe and go it alone, because we don't have a hard time, and we don't lack anything from birth, because our parents have accumulated enough wealth for us, and our parents won't let us suffer like this. When we choose a partner, we always want the other person to be financially better.
When there is no car or house, as a passive man, it is basically difficult to find a wife. Even if you really like women in two of a kind, your parents are very sad. No parents want to give your daughter to you. Your life is insecure and you have no financial support. This kind of life will be very sad. Don't talk about cars, you have to have the most basic houses. If you don't even have a wedding house, rent one.
It is normal that people are selfish nowadays. Everyone wants to live a good life, especially girls, who are delicate in the eyes of their parents. When they didn't marry you, although they were not as rich as oil, they certainly didn't have to worry about food and clothing. After marrying you, they will share the economic expenses with you. No one will want to.
