From 01.01.2015 until 31.07.2015 - we've gotten a total 195,723 Refugees, an estimated 500,000 will arrive for 2015.[1] Estimated costs will be around 5 Billion. For a comparison the Hartz 4 (Social Welfare System) had a total of about 32 Billion in 2013. [3]. Of all the refugees the majority come from Syria (~22%), and Irak / Afghanistan (~10%), which are countries with ongoing conflicts. [2] 39% of the refugees are coming from (Serbia / Kosovo / Macedonia / Albania), which have no listed ongoing conflicts according to wikipedia. The rest come from various countries the world over with around 1.7% from Nigeria and another 1.7% from Pakistan, which also both have ongoing conflicts.
So those are the facts, according to wikipedia and the BAMF (Office for Refugees and Immigration).
Now for the IMHO part :) The biggest problem currently with the whole thing is that we've known about this issue for a very long time [4], and no one prepared at all.
Even now nobody seems to have a plan about what to do with the refugees once they get here except give them food, housing, and living money, which personally I have no problem with as long as there is a plan to assimilate them into society, teach them german, get them jobs, etc. Why do I think some germans are upset? I think a lot of people have problems with the fact that this seems like another Hartz 4 type system where german tax dollars are going to pay for people who sit in the house all day and sponge off the system. Also, I think the media is just making this perception worse by showing thousands of refugees sitting around in camps or walking into Germany where they immediately get handouts. Also its easier to rationalize a Harz 4 system when its for "yourself" i.e. family or other native germans who have also paid money and hard work into the system. It becomes less and less easier to rationalize this goodwill when you're giving handouts to people from other european countries (yes, as a EU citizen you can get on german Harz 4 if you want), and even less still when the people don't aren't even part of the EU. At least thats what I think is actually going on here with the negative attitudes...
There are open commercials against "foreigner hate" but seriously who would have a problem with this if instead of those commercials they would just show the refugees getting jobs and starting to work?
