"Giving inheritance away to the scion of the wealth generator ... "

===

Also the guy who had a small business operating out of a building that he owned on what happened to be highly valuable land. 

He retires, liquidates the assets including the property and is left with, say, $15 million. Not an insignificant sum, but also not a ton when it comes to liquidating the assets of what is likely a relatively small business, especially if it involves real estate.

His two children receive the proceeds, but "they could not possibly (spend) it in several lifetimes." Unless, of course, they choose to donate or invest it or use it to expand or create their own businesses, or spread it among their own heirs. Either way, it's theirs.

How it becomes yours or mine is unfathomable to me.
