It doesn't matter if the man's family is really poor, but it is unreasonable to say that he can only get 8888. Who can be so poor? Generally speaking, the man has to solve the house problem. The reason why his parents are unwilling to pay may be that they are not optimistic about your marriage.
This is not so much the attitude of the man's parents as that of your boyfriend. There are not many children now. If the son gets married, Parents will take out the money at the bottom of the closet. As long as the man makes up his mind. Parents will compromise.
