The employer gives you a salary, then they have to pay on top of it ~30% of INAIL, INPS etc. (pension, health "insurance" including sick days and so on) and ~10% of TFR (fund you get back at the end of your career.) In the U.S. those are costs you have to remove from your salary.
So, 3000 euros a month would be 6000 euros before taxes and if you add the other employer costs, it's about 10000. Now convert it to dollars and you have a 130000 dollars a year.
