Construction costs are currently skyrocketing

If this continues like this in general, 7k net will be a "low" income for quite a while. Of course, it's enough for everyday life. But 3x on vacation + children and the associated consumption will initially have to be dropped and the money will have to be used more selectively. Whatever the personal priorities may be.

After parental leave, we end up with 7000k net (both then 80% part-time)

And I am aware that despite the low salary

Sorry but have you been drinking? (No offense)... 7k net is something like 80% of families do not have as mentioned...

7k is just average now, you won't get that without an inheritance.

Where exactly? Frankfurt or Munich? In rural areas even master's graduates (both) have to see if that much is paid...

..and then later 7000 € both in part-time Please let that sink in again what you wrote there. (Says someone who probably has the least income here in the forum)

Shall we now argue about kitchen prices with our low salaries? ;-)

Has nothing to do with battling. Anyone who thinks they "have to" rent with a household income of €7000 has not really dealt with the topic. We have significantly less and can quite comfortably afford our property. Admittedly, it is the wild East, but the construction costs here are the same as the rest of Germany.

Do we want to fight over kitchen prices now with our low salaries? ;-)

No, one could also simply stay grounded and look outside of one's bubble to see what else is possible.
That you apparently have a problem with this is up to you.
