That's an exaggeration. A non-working family (not sure what immigrant has to do with it) does not have access to the same quality of life than a working family with salaries of 60k. Sure, health and education-wise they both enjoy the same benefits, but for sure not in housing as you mention in your third point.
60k is 2800 € net per month. A refugee on welfare would get approximately 400 per adult plus 300 per kid plus rent paid (and free insurance). For a family of four this is 1400 Euro. Let's assume 1000 for rent in a city. This is 2400 so basically the same that you have.
Fact is, even as a full working engineer your available money is not significant different. A policeman with two kids and his wife not working has less money as such a family living on welfare. In fact, he would qualify for subsidiary income.
And we are not talking yet about refugess with 4 wifes and 23 kids.... http://www.rhein-zeitung.de/region/lokales/westerwald_artike...
Police earnings are a bit complicated but basically everyone with kids gets more than welfare after initial training. Some young police officers from Berlin (rightfully) recently complained that they are below that but this is the exception.
Does it apply to refugees only, or to everyone?
But gotta feed them "refugees", eh?
Now, where I do see the problem is that most of the housing is owned by people renting it out (check out Germany in this list [1]). My whole building is owned by the same guy who I guess lives quite a relaxed life out of my rent, while producing nothing. If you want to fight the increase in living costs, I'd start there.
I have no problem with feeding and sheltering refugees.

Because it's tax smart. If you own real estate, all repair, maintenance costs etc. can be deducted from your taxable rental income. On the other hand, if you live in a property you own, all maintenance costs are paid from your after-tax personal income.
Laws do no change market realities.
How many immigrants do you want to accept? 1 Million? 10 Million? 100 Million? 1000 Million?
Based on the population and fertility rates of the middle east and especially Africa, 1000 Million (1 Billion) would be a number that is not impossible. But, don't you see a problem there?
