Frank - who is this 'they' who should have forced Jeanie's ex to pay? In the 60s there was no legislation to help in this situation nor legal aid to allow a destitute abandoned wife to employ a solicitor. Back then everything worked on the assumption that a decent man would always support his children and would make provision for his ex-wife on divorce. However, many men were not decent and even today it is difficult to enforce payment of child support from a reluctant man - some go to great lengths - going abroad, becoming unemployed or self employed - to thwart a court order.
Frank - I repeat again that you have had a charmed life (and I do not begrudge you the fruits of your labours and thriftiness). What is annoying is when you, who have lived your life in a comfortable middle class bubble, tell people what they 'should' have done 40/50 years ago, often citing options which were not possible for them because they were female, disabled, had no parental support or whatever. I could not go to university not just because my parents could not afford to support me until I was 21 but when my mother had to give up work following an accident, I had to leave school and start work at 15 to replace her missing wages in the very tight family budget.
Funnily enough, I have no chip on my shoulder and have led an interesting, varied and enjoyable life. In fact I rather pity you with all your worries about extracting the last penny from your investments, keeping your house in the family, care home fees, wills, battling with income tax and pension people. When you have just enough to get by on you are spared these worries and can concentrate on enjoying what you do have.
