”Rrgulation never works”, is a very shallow take. It could mean anything. China is an autocratic system. Is that working? The US is going in that direction.
On top of that, Europe isn’t a country. To have less regulation, you need more of it. Unifying regulations, or else you have dozens of completely different jurisdictions. To a large extent, you still do, even with the EU. You can’t sell to the general public in English. There are so many more things holding Europe back than ”need deregulation”.
