>>90% tax above one million dollars. With you on that one. Huge inherited wealth (usually related to booming property prices ) and low taxes is really stitching up the young and the poor.
The UK already has 40% inheritance tax on estates more than GBP325K unless you pass the estate to a spouse, charity or a few other exceptions. This year they're increasing the threshold for bequeathed main residences, with plans to excuse the tax on homes up to GBP1M by 2020.
The problem with excessive taxes on estates, is that they're easy enough to avoid by depositing assets in an eternal trust. Also worth observing the effect when estate taxes once drove family inheritors of UK stately homes to the point where they could not afford to maintain the asset, with the National Trust taking over more than a few distressed estates (and denying estate taxes ever again since the National Trust will never die.)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
