I think it's a bit more complicated. Romania has always been a poor country and highly reliant on EU money, and cutting off that money would have been bad for everyone. And back then most people didn't truly understand the devastating effects of mass migration from third world countries.

I believe we will see a lot more people taking a hard stance against migration this time, even if it affects the money they get from the EU. While Romania has been much less affected by migration since they're all going to West Europe it's very easy to see proof of its negative effects on the internet.
