What values are we talking about? From a few sites, it seems ~31% (employer + employee), which doesn't seem that high relative to other European countries.
Yeah, well, as a Portuguese I'm paying 35% in SS contributions, plus more than 10% in income tax if one earns more than 920€/month, so I feel your pain.
It wouldn't really bother me if so much of it wasn't wasted, though.
