Barry didnt buy a small floundering drug company. When my father passed, his group of cos was the largest generic drug manufacturer in Canada with over a million dollar in sales in 1965.
He played the family card and offered the Royal Trust Co. an option to me and my brothers, which he never intended to honour.
All the billions my cousin made never brought him happiness. He screwed a lot of people and made many enemies. But in the end, he went mad/crazy. I sat across from him during an examination for discovery last year and he was clearly losing his mind. Maybe....the money was cursed, because he stole from orphans. Behind every great fortune is a great crime!
I would expect - IF I ever would expect at all - to get 20% of the value of your father's group of companies
at the time he unfortunately died much too early.
The chance for you and your brothers to get a job at the age of 21 at one of the companies your father owned
when he died, you hadn't been given. BUT certainly you are not able to claim objectively, whether you ever would have taken this chance for longer than a probationary period and whether you would have been successful, IF . Think of BS' own children: no one is working in his business. There may be a reason and you might have had the same reason for quitting work with BS at an early stage.
After all, BS had cared for you and your brothers with the help of his money again and again. Do you think your own father would have generously funded you and your brothers
without reinsurance over tens of years? I think, he wouldn't have as well. Your father would have tried to teach you and your brothers responsibly handling with his laboriously earned money as BS did, I think. Which intelligent, busy, wealthy father would not?
You and your brothers had a nightmarish childhood, it seems. I'm very, very sorry about that!
Though I don't understand why only your cousin Barry should be to blame for those very unhappy years and your further life, you and your brothers - 4 orphans in the care of adoptive parents - had to endure. I think, more of BS' money would not have really helped you and your brothers. The ambition to become successful of your very own would have helped - the wrong view of your life like "shoulda-coulda-woulda" may have been poison for you and your brothers and will remain poison forever, IMO.
As you said: BS couldn't buy happiness with all his money. Neither you and your brothers (s-i-l), as bad as it is.
