@jwildeboer Paul Magnette is het president of the PS in Belgium. Most of their previous propositions to tax the rich in Belgium ended up with taxing the higher middle class. In a country with some of the highest taxes in the world, it will be hard to convince people to sign this proposal, specially when it's coming from a party that ruled Belgium for a long time and was never able to fix the issues here.
@stroobl And yet Belgium ended at over 94%, so almost made it. An EU petition does not result in changes in national law, so reducing the EU initiative to one of the initiators being from Belgium and from a party you don't really like isn't helpful, IMHO.
