I have recently saw an older recording of an economist arguing that he does not know of any "successful implementation" of the solidarity tax. I have searched a little bit about this and found this article which mentions the criticism related to the implementation of this tax in France:
The solidarity tax has been criticized by many who believe it drives away the wealthy from France or incentivizes the rich to find ways to evade taxes.
I am wondering the economist is right.
Question: Has the solidarity tax been successful in any country?
To make the question more answerable (clear, not too broad):
- successful = the collected amount > estimated loss through wealth being moved outside the country + estimation of tax evasion + cost of collection
- European country
- no special context such as warfare, German reunification or similar events
- after WWII
