I don't agree with your statement at all. Crime, rape, and instability are all inevitable, regardless of your origins. It is almost that you're implying to say that all third world migrants will have the same destructive mindset, and that is completely false. The amount of good can be just finely replicated as the apparent evil that is dwelled on. To be factual, those same third world migrants are the ones that help often help us imprison the wrongful delinquent beings. To go even further, many relationships regarding long distances between family/friends would almost cease to exist in visitation if that is the proposed case. So the term "keeping them out" sounds almost narrowly one-sided.
"Sweden began opening its doors to Muslim immigrants in the 1970s. Today it pays a high price for having done so. The group suffering the severest consequences of such an open door policy has been Swedish women.
As Muslim men immigrated to Sweden, they brought with them an Islamic culture sanctioning rape. It is a culture bad enough inherently in the treatment of its own women. Under sharia, Muslim women serve little more purpose beyond catering to their husbands’ sexual demands. A non-submissive wife runs the risk of being raped by her husband.
But under sharia, this rape culture also impacts upon Swedish women as they are “infidels” and, as such, are – according to Allah’s teachings – sanctioned targets for rape by Muslim men. Such an Islamic belief system has born witness to a drastic increase in rapes in Sweden – more than a thousand fold – since first opening its doors to Muslim immigration.
A 1996 Swedish National Council for Crime Prevention report bears this out.
It noted that Muslim immigrants from North Africa were 23 times more likely to commit rape than Swedish men. It is no wonder why today Sweden is deemed the rape capital of the Western world.
Even more shocking, however, is the political correctness overshadowing the reporting of these crimes. Sensitive about accusations of Islamophobia, the Swedish press refuses to sound a warning alarm for native women about who these sexual predators are. Thus, when a Muslim commits a rape, the media only refers to him as a Swedish male."

"An epidemic of rape cases across Europe has police in the U.K., Norway, Sweden, Germany and other nations worried. But you won’t hear much about it in the U.S. mainstream media because the epidemic is a byproduct of the influx into Europe of a million, mostly Muslim, migrants.
A growing number of women and young girls housed in refugee shelters in Germany are being raped, sexually assaulted and even forced into prostitution by male asylum seekers, according to German social work organisations with first-hand knowledge of the situation."
