The problem with most types of tax scenarios like you describe, is that the truly wealthy will always find some place else to reside where they can escape the taxes. They are the ones with the means to do it. Tax systems that target "the rich" nearly always net less than they should on paper for this reason. This happens in the US routinely. People flee states like New York and New Jersey and move to places like Florida. In general, the wealthy will always be able to afford and find a way around things like the inheritance tax and the housing taxes you describe. If the tax is severe enough, people will take drastic action. The above aside, from an economic perspective, you don't want to discourage people from buying "stuff" with their money. In your example, I'll take private jets and big houses. Lots of people at various rungs on the economic ladder are employed to make and support those things. From the guy that drives the fuel truck (or cement mixer) all the way up through the engineers who design the plane (or archtects who design the house).
