I do feel worried for these people that support remain so ardently, because I can not see in the longer term how the euro will possibly survive another crash like the one we had in 2008.
As it is, most of the eurozone has not recovered from the last crash. Countries like Italy will be forced to leave the euro, and have in fact already set up a new currency in anticipation. Had Greece done the same prior to 2008 they could have had a softer landing with the IMF.
The EU project has failed in some ways, it has delivered in other ways. The prosperity of all types of nations being hemmed into one currency has been the biggest disaster, especially for the weaker smaller countries. The benefits of free travel has benefitted eastern european and those companies looking for cheaper labour.
On balance many changes will need to be made within the commission for it to survive, but I fear the commission lives in a bubble, and only the reality of a biting recession across the euro area will pierce through and and force the reforms that are so badly needed.
