Let's not forget Big tech is also fueled by the rest of the world and Europe.
If you walk into a bank in Europe and have some money to invest they will sell you mostly debt and the "Magnificent Seven" or a funds with those stocks inside.
The EU is ridiculous when it says it want to built an alternative because it's entire financial/banking system end up fueling the saving of its citizen into those companies.
This is also why we end up in that absurd situation where the Mag 7 make up 1/3 of the S&P 500 market cap.
If the EU is serious about offering an alternative (which I doubt) it needs to offer a sustainable path for its people to invest in it. Not do another fake program where insiders will grab some public money and get nowhere (it has been tried for 25 years).
