I am referring to the whole shebang. From what I know, pension and unemployment insurances are mandatory. Am I wrong?

Now, with pension and unemployment insurances, will the tax bracket be higher than 30% for 100k ?

You are right, no one sensible would go without the health care portion. But some people (moi) don't trust pension with governments. (Argentina, Hungary.. etc)

Now, if those things are mandatory, how much would be left of a 70k salary? Still on the 30%?
