You may be confusing your salary with what your boss charges clients. Or, it may simply be that you are from somewhere where the economy is different.
While my boss charges something like EUR100 an hour, I make less than 25% of that (after taxes).
O.t.o.h.: The salary is quite competitive around here (41k EUR a year, 40hrs/wk, 25 days off)
Edit: Note that this 41k/year pretax salary in The Netherlands does not include the contributions your employer makes for you to your social security/pension/disability insurance, etc. That being said, even after all those it's not yet near 60 bucks an hour.
