Too many idle rich anyway, living on the hard work of others with no appreciation of what it takes to earn that kind of wealth.
With few exceptions, it is never a good idea to leave your children with so much money that they never have to work for a living. They typically get spoiled and end up with wasted lives. Also, they tend to be very liberal, as they will never know what it is like to earn their own wealth on their own hard work and merits.
