We need taxes for all - also the super-rich.
"Tax the rich" is an official EU petition. The EU Parliament has to deal with it when successful.
7 EU countries must reach the quorum. And in total 1M Votes are needed. Check yours in the chart and share, cross post etc.!
The petition calls for the introduction of a wealth tax on very large fortunes. Sign the petition here
You didn't read that paper. From fast skimming I can clearly see that their simplified model didn't check for impact of skill at all.
It says nothing about real world except there's a wealth concentrating factor of being ahead. Other factors are ignored
The key thing is that this paper looks at generational wealth accumulation. Even if families which consistently churn out stellar business people were in any way common (data says otherwise) that effect is still completely overwritten by already being ahead. As a billionaire kid, the extent of business skill you need to have to not lose everything is to hire people who have business skill and then slurp Caipirinhas on your yacht from your ample, ample dividends. And if you lose everything, well, you're losing it, on aggregate, to other billionaires, so wealth concentration still proceeds.
