With regards to this "Prudential Saga", what needs to be done is the PolicyHolder (or the son of that PolicyHolder) needs to sit down, read, think and examine what constitutes their Policy Contract, and to lay down all the collateral that they have and evaluate if they have been any material breach or misrepresentation on the part of the insurer or insurer's representative at that point in time. If they are unable to do that themselves, they need to get help from someone else that can spend the time, effort and energy to do that for them.
Decades ago, endowment was the fashionable financial product/tool, just like BTITR where I=ES3,.... is fashionable now. No one will be able to tell if 2 decades later if the I=ES3,....is the still the correct decision.
Having said above, I do agree the I=ES3,...Vanguard Index ETF....etc....makes sense now.
Financial well-being is personal. Individuals will have to be responsible for their own decisions.
