This is the standard thing that xenophobes do when talking about how bad immigration is. They tell someone to take a loot at X. Where X is a place the listener probably hasn't been to and doesn't really know anything about.

It's like if I was talking to a bunch of factory workers in Kentucky about how bad marijuana is and said "just take a look at Holland!" They'd have no fucking idea what it's like in Holland but someone claiming to be an authority just told them the situation was concerning.
