There have been a lot of news articles that some refugees travel every month from one country to another (in Europe) as they found a way to collect benefits in all countries and this freebie is working very well for them while Europeans have seen their taxes go sky high to pay for the refugees.
Keep in mind that most of the refugees are economic refugees and not the ones fleeing war zones!
