Well yes, and no, in most cities in Spain* with 35k€ you would probably be in the top 5-10%. Average salary in many cities is 15-20k€, so with 35k€ you'd be relatively very well off. Of course compared to international dev salaries it's low, but that's not relevant for all.
As a funny data point, my first salary ever as a developer in Valencia, Spain was 12k €/year (6k € part time), and I was very happy with it since it was while I was in college so it was all for fun and savings. Some day I should share my salary evolution, it's just crazy.
*I'd say on average if you exclude Madrid/Barcelona
You can get more than 35k in east europe. South europe is not much tech developed and pay is indeed low. In northern europe you get more but pay more in tax so its not really much higher.
