Now that’s just hyperbole, and factually wrong, too. The EU has managed amazingly much over its existence. After WW II, it managed to keep peace, establish the worlds largest single market, enabled free trade, allowed citizens to move, live, and even work in any member state; it implemented regulation that makes food, drinks, and products some of the safest to consume and use on earth; it devised standards that are globally adhered to; it funds art, research, and urban development across all member states (as the Brits painfully realised); it distributes wealth in Europe, making the union stronger overall; and that’s just a small sample.
There’s lots of things in dire need for improvement for sure, but downright dismissing the EU as having achieved nothing is just spite and not helpful. That attitude got the Americans where they are now, and I sure don’t want to go there.
