Pretty much this.
There is always going to be corruption and abusing the "less fortunate", but countries like Hungary/Romania are definitely the ones who are by far the most responsible for this type of criminal activity/abuse.
The governments of countries like Hungary/Romania have, for decades, managed to fool their own people by putting the vast majority of the blame on outside factors like the EU, while in fact it is their own corrupt politicians who are exploiting their own people.
