My husband does not take out money for my or children's expenses from joint business, fearing that the other partner will also withdraw the same amount of money and business needs money for growth. How do I deal with the situation?

But Its been 14 yeras of my marriage , He just takes out money for food and daily needs . Children education and other expenses are covered from my salary. I am bothered since every body is growing in jobs and business , my husband is not at all withdrawing money and now after 2 years the other partner son will also join the business. My question is Then also business will give him salary but why not now it can't be withdrawn.
