Doing financially well as a breadwinner in your family is not sufficient enough to encourage your financial growth or stability when you don't optimize to make provisions on how your dependants can also stay financially independent to themselves because over billing can actually weigh your aiming down.
I get your point. The issue you raised presupposes that in a family where only one person is rich, that family is poor. To help oneself become financially stable, one has to better the lot of one's dependants by teaching them how to fish by themselves and not throw fish at them. As Africans, we live communally by the extended family structure and that makes it difficult not to have dependants. We can't escape that. However, wisdom is profitable to direct on how to lift them out of penury without distabilizing one's finances.
