If you have a younger brother who doesn't date anyone and earns less money, what do you say?

A person's self-esteem is very strong, and it is a good way to hit his self-esteem For example, let a person (this person is definitely going to be a bad person, it can be you or your family, or it can be an ordinary friend. Friends are better than family, and then friends will be fine. To some extent, he showed contempt for him economically, even verbal humiliation (be careful to be beaten, or bet, of course, the result of losing will be unbearable for your brother). He doesn't want to be trampled on like this, so he may try. This method is an idealized one that I think of, and I don't know if it will work. Do you think you can give points?
