Oh do tell. I'd love to know how it's propaganda to describe basic economics and global tax that dominates the majority of the world.

You don't reach a solarpunk future by pretending the status quo isn't what it is.

"(Londoño-Velez and Ávila-Mahecha, 2020) Using tax data linked to leaked information on offshore accounts located in Panama (the ‘Panama Papers’), they find that individuals incorporate offshore entities and use these to reduce their reported assets by 7.7% in years in which these assets would result in a wealth tax liability."

From https://www.wealthandpolicy.com/wp/EP5_BehaviouralResponses.pdf, which spends an immense amount of time understanding the behaviours when the wealth of the rich is threatened (FWIW, it's a deep paper with at times conflicting information, and some of it is scant because obviously the rich like to have a tangled web that is hard to unpick).

The rich have an endless array of options for avoiding these taxes. From offshoring to actually leaving.
