Adding a huge VAT rating would in theory make no difference because apparently 'these are people for whom money is no object' so if that's the case and they want the plane that badly they can pay an 'enhanced price for it'.
With all due respect, when "theory" meets reality, the manufacturer will build the thing where the taxes are not predatory, and the countries with the predatory taxes will not only get zero tax revenue, but will lose a good number of high wage jobs. The politics of envy are almost always self defeating.
