My brother likes to start a business. Before starting a business, he had spent all the money in his family and borrowed tens of thousands of dollars in debt, which he never paid back. He looks like.

How old is your brother? If you are an adult over the age of 18, tell him that you are an adult, and you have to bear some things yourself. Family helps you, that's affection, that's encouragement, that's to let you accumulate some experience. Everyone has his own life and can't always sacrifice for one person. For adults, in fact, family members have no obligation to always help you. My brother has been defeated and fought many times. Let him think calmly and find out the reasons for his failure. Starting a business looks simple, but actual success is not that simple. You let him think about the problem first. Entrepreneurship not only needs money, but also involves many aspects, such as the feasibility of the chosen industry in the future and the wisdom of entrepreneurs. That's what you said. Let him find a job and work for a period of time, say, one or two years, so that he can have some understanding and cognition of society and things. Then you can ask him if he still wants to start a business, and then the family can discuss it together. Maybe at that time, your family will have a new understanding of you, and it may be easier to agree to your terms. That's all.

I hope my answer will help.
