Fully agree. I have been able to collect some signatures among my friends and relatives (in Germany). Unfortunately, I don’t know how I could help in other countries / languages. At most with upvotes of the relevant posts and in general spread the word.

And I have just noticed that the initiative’s website (https://www.tax-the-rich.eu/) with all the important information is only available in 6 languages. Polish is not included. That could be a reason. Things like this are an oversight we need to address (next time…).
