Sure, the Nordics tax the rich at high levels. But the Nordics also tax everyone else at high levels, too. While the former may be politically doable, the second is not.

And while taxation is one of the reasons Nordic countries are middle class, it's also because until relatively recently they were quite homogenous. And their taxation and welfare systems enjoy broad approval. (In fact, right-wing parties don't even focus on them.) They also don't have the federated government we do.

So, your solution is about realistic as mine.
