Narrative:

Tower cleared us for takeoff shortly after preceding wide body was airborne. We were given 'fly 220 heading after takeoff at shoreline' as was the clearance for preceding wide body. Just after rotation at approximately 100' AGL we encountered very strong wake turbulence causing a sharp wing low deviation. Captain regained control and we climbed in and out of preceding aircraft's wake turbulence for quite a while. We informed lax tower of our wake occurrence and mentioned spacing was not sufficient. Tower controller rudely and unprofessionally responded 'your only requirement is 3 miles separation for takeoff'. Separation behind wide body aircraft gets worse and worse each month. FAA cannot afford another loss of life over this chronic problem. Encountering wake turbulence at 100' AGL at 765000 lbs near max takeoff weight with 325 lives is unacceptable. Increased separation behind wide bodies for all aircraft. Why does a wide body have reduced separation behind another wide body?
