@mina I tried, but could not find any meaningful information here on what exactly this means. What is considered "rich" or "wealthy"? It does not establish any baseline from which to foster further conversation.

I'm especially interested because I'm an upper middle class earner, but I already pay 60% of all of my income to tax - so exactly what would the tax for the "rich" be, if in most EU countries people already pay more than half away to tax?
