Many big business houses are family run-Reliance,Godrej etc.Succession planning is a struggle:The big corporate houses like TATA Sons, Infosys, and many other companies are struggling hard to find the suitable alternate leaders for top-level positions.
US has no such issues about succession planning in huge companies like Microsoft,Apple etc.
Exit of Mr. Bill Gates and Mr. Steve Jobs and others did not hamper the business house performance, also it did not affect the investors
Personally I feel: Leaders, are reluctant to identify the successors and in shaping them for the next generation of businesses.
In other words, it is an ego-problem. It may be intentional by ignoring successors, thinking that they are the rivals.Also they want control in family only.

Pressure from market which needs long term business continuity plans will make sure that succession plans are made and people identified.
Professional business cannot run without long term planning.
