No way you can use 1300 hours average to compare with 50~60K average salary.

I just assume you took this number off the OECD chart which explicitly states that you can't compare between countries because they have different methods of evaluating the numbers. (Ironically I have only seen country-comparisons from this data)

You won't get anywhere near 1300 hours without counting all part-time, half-time workers who obviously don't get the full salary. The standard is 40 hours per week (37.5 if generous) with 30 days of paid vacation. That is 1700+ hours per year.
