It's possible to earn far more than 60-70k a year in Germany as a SWE. In my city, Munich, total cash compensation packages range from 85-110k Euros per year for 5-10 years of experience. The base salary trends to on the lower end, but there can be significant bonuses (company bonus, August vacation bonus, and Christmas bonus. For example st BMW, each of these are typically a month's extra salary). In addition, if your position is unionized, it's possible for you to accrue substantial overtime to further increase annual compensation.

And it's possible to earn far more than 40k EUR a year in Poland as well. Google Warsaw starts at 45k EUR for new grads, and you're looking at 80k EUR for senior software engineers. There are a few high pitching companies that try to match that. I was rather pointing out the typical case that covers most of the workers.
