100% Inheritance Tax in Helsingin Sanomat

Today’s Helsingin Sanomat (the main newspaper in Finland) published an editorial that promotes 100% inheritance tax. I mean complete tax, not jus for millionares or something a bit like 100% inheritance tax. There are a few famous persons mentioned who support the tax and also one Finnish professor of public economy, Matti Tuomala, whose text about it started circulating again in social media this year because Finnish government is going the opposite (wrong) direction and redcing the tax.
