1) Most wealthy people have their money in their ventures - not directly available for private use, like cash in a bank account. I don't see how a cap would help in this case, as they can spin off multiple ventures, all still controlled by them. It would help to keep the economy going, but not by much.
2) People will find ways to hide their wealth - taking away their money when they die is an obvious threat to them and their children. It may work in the long term with the right control and incentives, but corruption (i.e. bypassing the law) will be extremely high in the beginning.
