(Proverbs 13:22 KJV) A good man leaveth an inheritance to his children's children: and the wealth of the sinner is laid up for the just.
I think it is interesting that the idea of leaving wealth skips the children. Based on reading and listening from sources outside the Bible, I have heard people comment on how often children are spoiled by rich parents. The parents knew how to work hard but too often they think they are going to do their children a kindness by sheltering them from that lesson. Some learn it in spite of the handicap. Others are weakened to the point of destruction. When a child believes he is going to inherit a fortune, why would he put in the effort to train himself for success. It is guaranteed.
So? Instead of making life easy for your children you should be preparing them for the trials and struggles ahead. Then let them do the same for the grandchildren.
