@lesechosfr.bsky.social devrait connaitre la différence entre la position d'un éditorialiste et la position d'un journal! Le lien dans le texte est à une chronique de Simon Kuper qui d'autre part demande plus de taxation des très riches, mais ne défend aucune taxe spécifiquement.

This is unbelievable! I know nothing at all about programming. I downloaded Cursor. I gave it instructions in plain English; it asked for details and within five minutes (I swear) it had built a simple web app. I did no coding whatsoever.

Do I understand correctly. Harvard corrupts the minds of its students. The Trump administration wants to protect international students from this corruption, while making it more accessible to American students?

The election of Cardinal Prevost as pope is prophetic. At the time where the US turns to "America First", the pope is an American who dedicated a major part of his life to serving another, poorer, country.
A lesson for all rich countries.

It seems that there is a distinct possibility that Musk has lost more through the decrease in Tesla stock than he saved the US government.
If they had thought this through, maybe they would have realized there was scope for a mutually beneficial trade.

I am so smart 🧠! I have figured out the strategy behind the tariffs. They will indeed cut off the supply of fentanyl to the US:
the gangs will turn to more lucrative forms of smuggling, like Chinese plastic bath toys. 💡

I have not seen any discussion of the administrative difficulties of managing the tariffs.
I cannot believe that this is going to go well. Setting up all the reporting, collecting and policing mechanisms is a huge endeavor.
Imported goods will be more expensive, but also some will never arrive.

I know that the Trump administration cares only about trades in goods, but still, the US has a huge trade surplus in educational services, and they are killing it. 🤷♂️

On top of the many other idiocies involved, it never seems to occur to these people that the workers who will make the iPhones, or the steel, or... will have to be taken away from some other activity. What is it that they will not be producing?

As a strong Americanophile, I am devastated by what MAGA ideology does to (and reveals about? ) the soul of America.

You should NEVER rely on one new fancy study to understand an issue or to choose a policy.
You should integrate it in your stock of empirical, theoretical and descriptive knowledge. It is a problem that such integration is not valued in academia.
