His numbers aren't false for France. I don't have my last payslip on hand right now but it show cost for employer and it's roughly the double of what you get after taxes. Something like 3k€/month before tax turn into around 2100€ for you but your boss have social charges on top of it so for him it's more like a 4k€ cost.
