Times change, and so do circumstances, particularly if in-laws enter the picture. As a general rule each generation should decide for itself. An example of this, which has been cited for decades, relates to a wealthy man whose assets were all tied up in a business which he thought was eternal. So he arranged that his heirs could never dispose of the stock. The business involved moving freight with horses and wagons, and his descendants watched it decline in value to zero.
Problems arise if parents try to force children into a business to preserve it.
This particularly happens if the father started or built up the business and his ego and personality have become deeply involved with his creation. Much misery has resulted from such cases. Maybe the heir or heirs do not have the temperament, the ability, or the desire to carry on such a business. Again, although there are some unusual exceptions, each generation should decide for itself. A tragedy can occur when children are required or think they are required to preserve some physical asset, such as the old family home or vacation spot.
