That post pretty much supports the whole "Europeans are racist against the Roma" to the point where I just couldn't finish it.
Because you call racism things that are not. You have your head burried as far in the sand as your run the mill republican.
If you implement the right policies, you can statistically diminish the criminality among a group of peoples and incrase the education, I think that we agree on that.
As colonisation and pretty much every occupation campain before has shown, you can also destroy the social structure of a group of peoples and reduce them to misery, and that create lasting damage in their society, with incrased criminality, decrased education, and lasting distrust of outsiders. One of the ways to do that is to segregate against them durably and systematically kill and supress their leaders. Displacing them work very well and was employed by Stalin with great success, forced conversion is a classic, changing their language and exacerbing ethnic and religious conflicts are extremely efficient too.
But just immigrating to a new place "en masse" and working low wage job will have a considerabe negative impact on any group of peoples, and you can only hope that their social structures will hold on then blend in.
I don't see how you can deny any of the above if you ever glanced at history, and half of our policies are based on that. That's pretty much what justify our "welfare states" and the money we're sinking in the "banlieues" and our multiple integration policies.
Population as Gypsies have been on the wrong end of the stick for quite a while and their social structure IS considerably damaged. And for black america, well, I'm sure you're informed of the hardship they faced. In neither case you can expect a criminality and education rate statistically comparable to the rest of the population, no more than you can exepct able to fly toward the sky.
If you want to reduce it, raise your sleeves and get your wallet out, because it will take money, work and time to repaire the injustice of history.
Btw you're wrong on something else, mostly. The american dream is still alive, it's just that since the fall of the nobility and of the last emprors, it's nothing special anymore, you can do it in Europe too, and more easily.
And lastly, from this article Last year, in total, British police officers actually fired their weapons three times. The number of people fatally shot was zero. In 2012 the figure was just one. Even after adjusting for the smaller size of Britain’s population, British citizens are around 100 times less likely to be shot by a police officer than Americans.
Another comparison?
Germany? there were eight fatalities in the past two years and 109 deaths by service weapons in Germany since 1998.
Let's take only white peoples shooting, shall we? The (self reported is this supposed to be some kind of joke?) statistics available tell us that there has been 326 white peoples killed in America last years. Let's take the entire population of america (316,1 millions) and divide it by Germany's (80.62 millions) and it's great, you can see that you're still more than 20 times more likely to be shot by the police than a German EVEN IF YOU DON'T COUNT ANY BLACK PEOPLES KILLED. Do you understand you've got a police problem now?
