Target rich environment.
Singapore, which became notorious for caning Michael Fay for vandalism during the Clinton years, doesn’t have an illegal immigration problem. Why? It flogs the illegals it captures, confiscates their assets, and sentences them to prison terms of up to 6 months. And no, they don’t get welfare benefits of any kind (unless you consider passage back to their home countries welfare). If the EU ever gets the backbone to implement Singapore-style measures, its illegal immigration problem will disappear.
They did it because they’re largely secular.
