๐จโโ๏ธ Optimistic news from the U.S.
I promise this newsletter wonโt start revolving around American politics, you get more than enough of that everywhere else. But since I wrote last week that I believe the United States will survive as a democracy thanks to the Americans themselves, I want to point to the Supreme Courtโs decision as an example of that.
As you know, the Court ruled that Trump does not control tariffs, Congress does. The decision was made by a clear 6โ3 majority, with two of the justices nominated by Trump among the majority. The Supreme Court is an extremely important check on abuse of power, and the fact that it is now willing to stand up to Trump is an optimistic piece of news.
