You talk as though there was some time that the people who lived in this land owned it all. They never did. Many businesses grew from the landlord class. Many large landowners still exist. Many magnates have massive fortunes. They don't seem to be the target of your wrath. Why is this? All didn't earn it (which in essence seems to mean that the money you get is fine even though it is given to you from backers that for some reason don't deserve it).

Inheritance tax can easily be avioded by transfering assets 7 years before death. So, by passing on assets to both Charlie and his sons there would be nothing, or little to tax. It is often called "idiot's tax" as it is so easy to aviod with foresight.
