So would your method be then to not let the money they inherit gain interest as you said making money off their money or just take most of it when its passed on? Either way their are ways around this via stocks and property that can be turned around and sold.
I don't really have a issue with kids getting money given to them their parents earned when they pass or before hand. Its no different then if my mom died and passed on the house and some money to me tho granted on a grander scale. I do however favor a inheritance tax on such large fortunes but within reason. Say daddy leaves two billion to his son then take half or so. The whole not allowing money to gain interest in banks tho i am not sure where i stand on that. I don't know how that would affect the banking system and economy as a whole.
