I lived in Russia, Georgia, few European countries. Even in Georgia trains are way more punctual, than in Germany. Moscow metro works like a Swiss-clock compared to U-Bahn/S-Bahn.
Maybe what you are talking about is true for some very pour Asian/African countries, but many middle-income countries have more reliable public transportation, than Berlin. Not to mention developed ones and China.

I've been to Central America, Egypt, Istanbul, Sicily, Spain and many more candidates that take a more lax attitude to daily life. Their public transport could certainly be better.

Berlin is not Germany. Berlin is badly run, constantly out of money (especially for infrastructure) and very different than the rest. Still, inner city public transport is generally reliable, if dirty and sometimes full of questionable people.
