By design European laws are superior to national laws. Leaving the union is also instant bankruptcy because all countries have very high level of debt which are only guaranteed because they are in the union.
European population is getting old and replaced by a migration coming mainly from previous African colonies.
Future paying for the past.
That seems to violate basic physics and accounting laws. It isn't possible for everyone to be in debt all at once, because when everything nets out then there isn't anyone to make the loans. Someone has to be producing the goods that get consumed.
These interests are currently ~2% for France. Which mean the debt is manageable and the interests can be paid with the citizen's tax and the music can continue to play. But once France get out of the UE, interests rates become 5% then the citizens tax are not enough to pay the debt, and nobody wants to lend money to France anymore because even at 5% interests the risk of default becomes too great and they risk not getting the full amount-owed back so nobody lends, and since their is no money in reserve, and they can't borrow it means they default => bankruptcy. France doesn't have its own currency anymore so it cannot print its own money which compounds the problem. National resources get plundered, citizens get poor.
It is a game of musical chair which is highly non-linear.
Uhm, Europe is not the US. We still have a lot of manufacturing. It varies by country - the UK unfortunately had structural problems, finance supremacy and a Thatcher who hated unions so much that she'd rather destroy unionized industries than have unions. Central Europe still does a pretty large amount of manufacturing.
Then why are we afraid of China and the US and cave in to their demands?
Why is german manufacturing output back to where it was in 2006?[1]

Meanwhile Germany's and the EU's short sighted energy policies have caused a lot of manufacturing to move outside the EU to places like the US or China.
The EU is in a very bad position right now manufacturing wise compared to how it was and how it could be. It basically never failed to snatch defeat from the jaws of victory for the last ~20 years.
Because they have no spine and no leverage/muscle on the international stage to throw their weight around and make sure they get what's best for them at the expense of everyone else the same way US, China, etc do.
They play the international nice guy at the mercy of US tech, energy and defence, and at the mercy of Chinese manufacturing after dismantling their own manufacturing, so they can't do anything radical that upsets either or risk massive repercussions, meaning they get treated as a doormat, constantly being taken advantage of by everyone.
