I guess there must be a lot of German speakers here, but for those who are not German speakers, it may be worth clarifying a couple things.

1) the €5,160/month (€69,120 per year and only €2,580 each) which is all net ... so, after the massive amounts of taxes, fees, and costs that are taken out of people's paycheck every month for all the "free" things people in the USA gush over so much. Although it is difficult to reverse calculate the gross income amount, not only will anything above €56,000 be taxed at 42% (yes, 42% of the work and value you produce over €55,000 will be taken from you ... and that's just the start, but which would take too much to explain here), it is reasonable to say that a couple, i.e., two people taking home €69,000 (or €34,000 each) every year, will be making a gross of about €110,000 (or €55,000 each) before taxes.

On top of those costs, you have to also realize that in Germany, as well as most European countries, you are paying what is effectively a ~20% sales tax that is hidden/obscured in the form of a Value Added Tax (VAT) on most purchases you make. What that amounts to is that not only are wages in Germany (Europe) roughly 70% (40-60%) of what they are in, e.g., the USA, but you are paying effective tax rates of about 30%-38% if you are making anything like a median income, and when you add up all the other labor costs and fees for the "free" healthcare that is taken out (the employer portion of which is a heavy contributing factor for the lower wages, btw.) then you are left with, as outlined about 55% of your salary, which then, when you spend it on anything, you are then, e.g., paying the ~20% VAT/sales tax, or, e.g., the 100% gasoline tax (yes, it's ~100% in most European countries and they are trying to drive it up).

Maybe that will provide some perspective to people who not only laud the "free"ness of what Europeans have when they get back from freeloading off European tax payers who funded the "cheap" public transportation that is heavily, wildly, and corruptly subsidized by taxes; which American tourists experience as "cheap" because they get to keep more of their money and they are not paying the full cost Europeans pay with the significantly lower net income they have. To most europeans, public transportation is not cheap at all (hence all the bike riding), let alone even convenient, but to an American who gets to keep thousands of dollars more of his income, it's "cheap", because it's an illusion that is rather fraudulent actually.

This all will, without doubt be an increasingly challenging reality Europe (that is the ruling class) will have to face and will do whatever it can to suppress. As Merkel has already stated and has essentially been the de facto governing policy as if it were the bedrock of the German constitution "read my lips, no taxes will be lowered"; it will invariably collide with the reality of the consequences of importing masses of people from abroad in order to sop up and absorb the excesses of the Hosing "Bubble", aka, Fraud, which was just shoved into "bad bank" closets and brushed under "toxic asset" rugs where they are all still festering and rotting out the whole world's economies.

This will all come to another greater head possibly, as the ruse, the facade of "social democracy" starts cracking and crumbling when, e.g., people really start getting upset that, e.g., their own citizens, many of which who are now pensioners, who rebuilt the country after the war, are receiving less pension than foreign nationals who violated laws and social compacts at the behest of the ruling classes as they are set up in free housing and provided free money that belonged to citizens and was taken from them against their will through taxes. The reality of the matter is that we are facing a threshold of a new kind of serfdom/slavery, one not of physical restraint or restriction or even total physical control, but one of shackles and slavery of taxes, a business model of slavery more like that which slavery is named after, one, once the whole world has been subjugated and brought under the thumb of the ruling class, will have no escape from even if you were so inclined to flee and leave everything behind you and your ancestors contributed to creating.
