This year 3 families I am friends or associated with, have been blighted by repossession or no funds to bury a loved one, due to no life insurance. 

All had/have homes that were bought using a mortgage.

The Male Parents in these 3 examples were aged 20's , 40's and 50's respectively.  They all have 1 thing in common ..... children. 

How can it be good advice or even allowed to enforce a huge financial burden on anyone, in the form of a mortgage, without life insurance cover incase of death of the mortgage payer ?

The PPI scandal was purely an income generation exercise by the banks. Lack of Life insurance has infinite long term effects on families who lose a loved one due to a terminal illness or accident.

How can it be morally acceptable to evict a young family of five because Dad has an incurable brain tumour, cant work and has no life insurance bound to the Banks mortgage ?

This is a National financial scandal. It is house buyers being poorly advised by financial institutions who should ensure, the lifelong transaction is safe and fair to all parties concerned.
