Future of Schengen?

[DavidB.]

The entire Schengen Area should be scrapped, and all European countries should go back to having border controls. Countries need to have borders, and they need to be able to control those borders.

Exactly this. Also lol @ the "holidays" argument. It was not so hard to carry a passport and show it at the border, and the "freedom" not to do so is certainly not worth the loss of sovereignty and the security risks.
