In terms of healthcare industry in Hungary: one worker does the same job for 700 USD a month and another for 1100 USD, the only difference is formal education and years worked in the industry. You can perform much better (by actually caring about the patients in those 12 hours you work) but you will get paid the same amount regardless. Of course if you have 3 kids (whether they are adults or not) then you do not pay taxes (or much less than someone who does not have kids or only has 2).
