Since the Mietendeckel went into effect in February my (already low) rent went down by almost 300€ per month - I have never experienced anything like that anywhere else I lived in. We moved from Tel Aviv to Berlin in late 2013 & even back then we left a crumbling, old 55m 2-room apartment in a worse location that costed more than our current 92m, 3-room apartment in much better state of repair & in a better location (in terms of transit access, schools, environment, noise, etc - the only significant advantage I can think of for our old apartment or neighborhood is that my parents & sisters lived nearby).
According to the first internet resource[0][1] I found (as well as anecdotal data from many people I know in both cities) wages are more or less the same in both (tech workers earn more in Tel Aviv but everyone else earns more in Berlin).
I would say while the situation needs improvement (namely more housing built & faster) it's hardly the worse I've seen & almost everyone I know in other major global cities suffers from a worse housing market.
